Re-enables interrupts (after they’ve been disabled by noInterrupts()) Interrupts allow certain important tasks to happen in the background and are enabled by default. Some functions will not work while interrupts are disabled, and incoming communication may be ignored. Interrupts can slightly disrupt the timing of code, however, and may be disabled for particularly critical sections of code.
Use the following function to re-enable interrupts in your program:
interrupts()
The function does not admit parameters.
This function returns nothing.
The code enables interrupts after disabling them.
void setup() {}
void loop() {
noInterrupts();
// critical, time-sensitive code here
interrupts();
// other code here
}
