# noInterrupts()

## Description

Disables interrupts. 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.

## Library Documentation

void noInterrupts()

  Disable interrupts.

  After calling this function, all user-programmable interrupts will be disabled. You can call this function before a timing-critical section of code, then call interrupts() to re-enable interrupt handling.

  See: | interrupts()

## Example

    void setup() {}

    void loop() {
      noInterrupts();
      // critical, time-sensitive code here
      interrupts();
      // other code here
    }
