For any questions regarding security, contact the Arduino Security Team. In order to provide secure digital services to customers, we at Arduino are committed to regularly monitor and update our services, applications, and infrastructure. In general, the approach to Security is aligned with Cybersecurity standards such as ISO27001. To ensure the highest level of confidentiality, integrity and availability, Arduino operates under a shared security responsibility model. The shared security responsibility model identifies the distinct security responsibilities of the customer and Arduino. In this model: * Arduino is responsible for the security of the Cloud infrastructure services provided to customers and the confidentiality of sensitive data. We provide such security via a number of best practices that all employee in Arduino follow and that are described in the following sections of this document; for example, but not limited to the following: * We limit as much as possible the level of access that Arduino employees have on customers data. * Security and privacy training are conducted regularly to ensure the highest possible level of awareness to Arduino employees. * Regular penetration and vulnerability security tests are performed to our infrastructure and services to assess that security practices in place are working as intended. * Customers are responsible for the security of their account, personal access credentials, and for the information they decide to store in the Cloud. Arduino recommends to pay particular attention to the following best practices: * Strong authentication: taking advantage of strong authentication can significantly help to improve the security of your Arduino account. Options offered by Arduino Cloud are: * Two-step verification: a second step to verify your identity during login adds an extra layer of protection to your account. Once enabled, you will be asked to provide your regular password and a digit code when logging in. It will be your responsibility to make sure that all relevant data to enter your account when two-step verification is enabled are properly backed up. * Social login: managing multiple accounts with multiple passwords might become problematic, which is why you can choose to login to your Arduino account using a social login that you already own. Via social login you can authenticate to your Arduino account by using your favorite social account without sharing any sensitive login information with Arduino. * Confidentiality: customers should make sure to not incidentally disclose personal information as part of the content they upload (for example when sharing a project or a sketch). While Arduino can protect confidentiality of information that is recognized as such, it can’t protect against information accidentally disclosed by customers inside customer-created content. ### Arduino Cloud services are ISO 27001 certified URL: https://docs.arduino.cc/arduino-cloud/business/iso27001/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/arduino-cloud/09.business/01.iso27001/iso27001.md Description: Learn about the Arduino organisations ISO 27001 certification and what it means.

The Fading example demonstrates the use of analog output (PWM) to fade an LED. It is available in the File->Sketchbook->Examples->Analog menu of the Arduino software. Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. This on-off pattern can simulate voltages in between the full Vcc of the board (e.g., 5 V on UNO, 3.3 V on a MKR board) and off (0 Volts) by changing the portion of the time the signal spends on versus the time that the signal spends off. The duration of "on time" is called the pulse width. To get varying analog values, you change, or modulate, that pulse width. If you repeat this on-off pattern fast enough with an LED for example, the result is as if the signal is a steady voltage between 0 and Vcc controlling the brightness of the LED. ### Bit Masks with Arduino URL: https://docs.arduino.cc/learn/programming/bit-mask/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/learn/03.programming/09.bit-mask/bit-mask.md Description: Bit masks are used to access specific bits in a byte of data. Bit masks are used to access specific bits in a byte of data. This is often useful as a method of iteration, for example when sending a byte of data serially out a single pin. In this example the pin needs to change it's state from high to low for each bit in the byte to be transmitted. This is accomplished using what are known as bitwise operations and a bit mask. Bitwise operations perform logical functions that take affect on the bit level. Standard bitwise operations include AND (&) OR (|) Left Shift (<<) and Right Shift (>>). ### Bit Math with Arduino URL: https://docs.arduino.cc/learn/programming/bit-math/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/learn/03.programming/11.bit-math/bit-math.md Description: Learn about bit math and how to manipulate individual bits in your Arduino sketches. > This article was revised on 2022/09/28 by Hannes Siebeneicher.

Embedded systems are microprocessor or microcontroller-based systems with a dedicated operational role. Rather than being made of separate components, like desktop computers, laptops or, gaming consoles, embedded systems integrate all the hardware and software necessary for a particular purpose. Nowadays, embedded systems are everywhere: automobiles, cameras, household appliances, and mobile devices are just some examples. Embedded systems design can be challenging since it combines hardware design, firmware, and software development, all in one particular device or product. In order to produce high-quality embedded firmware and software for a particular device or product, debugging is a necessary step in their development process. Debugging is the process of confirming that, one by one, many things that we believe to be true and functional in our code are true. We find a "bug" in our code when one our more assumptions are not valid. ### Designing Arduino Nano Hardware URL: https://docs.arduino.cc/learn/hardware/nano-pcb-guide/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/learn/06.hardware/nano-pcb-guide/nano-pcb-guide.md Description: Learn how to create your own custom hardware that is compatible with the Arduino Nano Family.

The pins on the Arduino can be configured as either inputs or outputs. This document explains the functioning of the pins in those modes. While the title of this document refers to digital pins, it is important to note that the vast majority of Arduino (ATmega) analog pins may be configured, and used, in exactly the same manner as digital pins. Arduino (ATmega) pins default to inputs, so they don't need to be explicitly declared as inputs with pinMode() when you're using them as inputs. Pins configured this way are said to be in a high-impedance state. Input pins make extremely small demands on the circuit that they are sampling, equivalent to a series resistor of 100 MΩ in front of the pin. This means that it takes very little current to move the input pin from one state to another, and can make the pins useful for such tasks as implementing a capacitive touch sensor, reading an LED as a photodiode, or reading an analog sensor with a scheme such as RCTime. ### Edge AI URL: https://docs.arduino.cc/learn/edge-ai/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/learn/09.edge-ai/edge-ai.md ### EEPROM Library URL: https://docs.arduino.cc/learn/built-in-libraries/eeprom/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/learn/07.built-in-libraries/03.eeprom/eeprom.md Description: Documentation for usage of the EEPROM library.

What makes an Arduino what it is? Many things, but one of the most important ones is the way every Arduino board is easily programmed with the Arduino Software (IDE). It is enough to connect it to the computer USB port and press the "Upload" icon to start a process that transfers your sketch into the Flash memory of the microcontroller. The behaviour described above happens thanks to a special piece of code that is executed at every reset of the microcontroller and that looks for a sketch to be uploaded from the serial/USB port using a specific protocol and speed. If no connection is detected, the execution is passed to the code of your sketch. ### Arduino ISP URL: https://docs.arduino.cc/built-in-examples/arduino-isp/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/10.arduino-isp/arduino-isp.md ### ASCII Table URL: https://docs.arduino.cc/built-in-examples/communication/ASCIITable/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/04.communication/ASCIITable/ASCIITable.md Description: Demonstrates advanced Arduino serial output functions.

Sometimes you need to do two things at once. For example you might want to blink an LED while reading a button press. In this case, you can't use delay(), because Arduino pauses your program during the delay(). If the button is pressed while Arduino is paused waiting for the delay() to pass, your program will miss the button press. This sketch demonstrates how to blink an LED without using delay(). It turns the LED on and then makes note of the time. Then, each time through loop(), it checks to see if the desired blink time has passed. If it has, it toggles the LED on or off and makes note of the new time. In this way the LED blinks continuously while the sketch execution never lags on a single instruction. ### Button Mouse Control URL: https://docs.arduino.cc/built-in-examples/usb/ButtonMouseControl/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/09.usb/ButtonMouseControl/ButtonMouseControl.md Description: Control cursor movement with 5 pushbuttons. Using the Mouse library, you can controls a computer's onscreen cursor with an Arduino Leonardo, Micro, or Due. This particular example uses five pushbuttons to move the onscreen cursor. Four of the buttons are directional (up, down, left, right) and one is for a left mouse click Cursor movement from the Arduino is always relative. Every time an input is read, the cursor's position is updated relative to it's current position. ### Calibrate Sensor Input URL: https://docs.arduino.cc/built-in-examples/analog/Calibration/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/03.analog/Calibration/Calibration.md Description: Define a maximum and minimum for expected analog sensor values. This example demonstrates one technique for calibrating sensor input. The board takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the loop. - Arduino Board ### Character Analysis URL: https://docs.arduino.cc/built-in-examples/strings/CharacterAnalysis/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/08.strings/CharacterAnalysis/CharacterAnalysis.md Description: Use the operators to recognise the type of character we are dealing with. In this example we use the operators that allow us to recognise the type of character we are dealing with. It is useful to check if a character is ASCII, or is upper case, or numeric, or it is a punctuation mark and so forth. The options available cover a variety of situations and this is demonstrated in the sketch below. Every character sent to the board through the serial monitor of the Arduino Software (IDE) is analysed by the sketch that returns all the information it was able to find. A single character may trigger more than one condition and therefore you may get multiple answers for a single entry.

URL: https://docs.arduino.cc/built-in-examples/display/RowColumnScanning/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/07.display/RowColumnScanning/RowColumnScanning.md Description: Row-column Scanning to control an 8x8 LED Matrix. LED displays are often packaged as matrixes of LEDs arranged in rows of common anodes and columns of common cathodes, or the reverse. Here's a typical example, and its schematic: These can be very useful displays. To control a matrix, you connect both its rows and columns to your microcontroller. The columns are connected to the LEDs cathodes (see Figure 1), so a column needs to be LOW for any of the LEDs in that column to turn on. The rows are connected to the LEDs anodes, so the row needs to be HIGH for an individual LED to turn on. If the row and the column are both high or both low, no voltage flows through the LED and it doesn't turn on. ### Control Structures URL: https://docs.arduino.cc/built-in-examples/control-structures/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/05.control-structures/control-structures.md ### Create a Graph with Processing URL: https://docs.arduino.cc/built-in-examples/communication/Graph/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/04.communication/Graph/Graph.md Description: Send data to the computer and graph it in Processing.

The SEN136B5B is an ultrasonic range finder from Seeedstudio. It detects the distance of the closest object in front of the sensor (from 3 cm up to 400 cm). It works by sending out a burst of ultrasound and listening for the echo when it bounces off of an object. It pings the obstacles with ultrasound. The Arduino board sends a short pulse to trigger the detection, then listens for a pulse on the same pin using the pulseIn() function. The duration of this second pulse is equal to the time taken by the ultrasound to travel to the object and back to the sensor. Using the speed of sound, this time can be converted to distance. - Arduino Board - Ultrasonic Range Finder - hook-up wires ### Pitch follower using the tone() function URL: https://docs.arduino.cc/built-in-examples/digital/tonePitchFollower/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/built-in-examples/02.digital/tonePitchFollower/tonePitchFollower.md Description: Play a pitch on a piezo speaker depending on an analog input.

The typical joystick is nothing but two potentiometers that allow us to measure the movement of the stick in 2-D. Potentiometers are variable resistors and, in a way, they act as sensors providing us with a variable voltage depending on the rotation of the device around its shaft. The kind of program that we need to monitor the joystick has to make a polling to two of the analog pins. We can send these values back to the computer, but then we face the classic problem that the transmission over the communication port has to be made with 8bit values, while our DAC (Digital to Analog Converter - that is measuring the values from the potentiometers in the joystick) has a resolution of 10bits. In other words this means that our sensors are characterized with a value between 0 and 1024. ### Introduction to the Serial Peripheral Interface URL: https://docs.arduino.cc/tutorials/generic/introduction-to-the-serial-peripheral-interface/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/generic/introduction-to-the-serial-peripheral-interface/introduction-to-the-serial-peripheral-interface.md Description: Learn about the SPI protocol In this tutorial you will learn how to interface with an AT25HP512 Atmel serial EEPROM using the Serial Peripheral Interface (SPI) protocol.

At Arduino, we place paramount importance on security when it comes to building the hardware and firmware for our physical products. Our comprehensive platform encompasses everything from hardware and firmware to development tools and cloud services. This article delves into the different facets of security concerns and outlines our approach to addressing them at each layer of our ecosystem. Several Arduino boards are based on a microcontroller (or MCU) architecture, and when connectivity options are provided by the board, there is usually a secondary chip taking care of connectivity aspects (e.g. Bluetooth® or Wi-Fi®). ### Serial to Parallel Shifting-Out with a 74HC595 URL: https://docs.arduino.cc/tutorials/communication/guide-to-shift-out/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/communication/guide-to-shift-out/guide-to-shift-out.md Description: At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers. At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers. This example is based on the 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more. (Users may also wish to search for other driver chips with "595" or "596" in their part numbers, there are many. The STP16C596 for example will drive 16 LED's and eliminates the series resistors with built-in constant current sources.) How this all works is through something called "synchronous serial communication," i.e. you can pulse one pin up and down thereby communicating a data byte to the register bit by bit. It's by pulsing second pin, the clock pin, that you delineate between bits. This is in contrast to using the "asynchronous serial communication" of the Serial.begin() function which relies on the sender and the receiver to be set independently to an agreed upon specified data rate. Once the whole byte is transmitted to the register the HIGH or LOW messages held in each bit get parceled out to each of the individual output pins. This is the "parallel output" part, having all the pins do what you want them to do all at once. ### Simple audio player URL: https://docs.arduino.cc/tutorials/generic/simple-audio-player/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/generic/simple-audio-player/simple-audio-player.md Description: Play audio using an SD card This tutorial demonstrates how to use an Arduino board (Arduino Zero, MKRZero or MKR1000 WiFi) to play a wave file stored on an SD card using the AudioZero library and the 10 bit DAC. - How to play a wavefile stored on an SD card. ### Simple RTC Alarm with a SAMD Board URL: https://docs.arduino.cc/tutorials/generic/simple-rtc-alarm/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/generic/simple-rtc-alarm/simple-rtc-alarm.md Description: This example demonstrate how to use the RTC library methods in order to do something when an alarm is matched.

In this tutorial you will learn how to use the SPI transaction methods. For an explanation of SPI see the SPI EEPROM tutorial. A common problem used to be that different SPI devices needed different, incompatible settings.

The tilt sensor is a component that can detect the tilting of an object. However it is only the equivalent to a pushbutton activated through a different physical mechanism. This type of sensor is the environmental-friendly version of a mercury-switch. It contains a metallic ball inside that will commute the two pins of the device from on to off and vice-versa if the sensor reaches a certain angle. The code example is exactly as the one we would use for a pushbutton but substituting this one with the tilt sensor. We use a pull-up resistor (thus use active-low to activate the pins) and connect the sensor to a digital input pin that we will read when needed. ### Two Port Receive URL: https://docs.arduino.cc/tutorials/communication/TwoPortReceive/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/communication/TwoPortReceive/TwoPortReceive.md Description: Work with multiple software serial ports on an Arduino board. Arduino boards have built in support for serial communication on pins 0 and 1, but what if you need more serial ports? The SoftwareSerial Library has been developed to allow serial communication to take place on the other digital pins of your boards, using software to replicate the functionality of the hardwired RX and TX lines. This can be extremely helpful when the need arises to communicate with two serial enabled devices, or to talk with just one device while leaving the main serial port open for debugging purpose. In the example below, digital pins 8 and 10 on your Arduino board are used as virtual RX serial lines. Pins 9 and 11 are virtual TX lines. The board listens on one virtual port (portOne) until it has read all available data. After that, it does the same on the second virtual port (portTwo). ### Two Switches, One Pin URL: https://docs.arduino.cc/tutorials/generic/two-switches-one-pin/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/generic/two-switches-one-pin/two-switches-one-pin.md Description: This example demonstrate how to use two pushbuttons and distunguish between them using only one pin on your Arduino There are handy 20K pullup resistors (resistors connected internally between Arduino I/O pins and VCC - +5 volts in the Arduino's case) built into the Atmega chip upon which Arduino boards are based. They are accessible from software by using the digitalWrite() function, when the pin is set to an input. This sketch exploits the pullup resistors under software control. The idea is that an external 200K resistor to ground will cause an input pin to report LOW when the internal (20K) pullup resistor is turned off. When the internal pullup resistor is turned on however, it will overwhelm the external 200K resistor and the pin will report HIGH. ### Unipolar Stepper Motor URL: https://docs.arduino.cc/tutorials/generic/unipolar-stepper-motor/ Source: https://raw.githubusercontent.com/arduino/docs-content/main/content/tutorials/generic/unipolar-stepper-motor/unipolar-stepper-motor.md Description: Learn how to drive a unipolar stepper motor commonly found in old floppy drives!
