Name |  | ### detachInterrupt()
Examples |  |
    int val = 0;

    void setup() {
      attachInterrupt(0, myFunction, RISING); // set myFunction to be called everytime
                                      // interrupt 0 is generated
      Serial.begin(9600);             // Starts serial to print data
    }

    void loop() {
      val = val + 1;
      if(val > 10000) {
        detachInterrupt(0);
      }
      delay(100);
    }

    void myFunction() {
      Serial.print("hello ");
    }
Description |  | It is possible to generate and attend external interrupts on the Wiring I/O board. There are 8 external interrupts, from 0 to 7 so there are 8 pins on the Wiring I/O board capable of external interrupts, 0, 1, 2, 3, 36, 37, 38, and 39 respectively. In addition to being regular digital pins, note that pins 0 and 1 are also used for the Wire library (TWI) and pins 2 and 3 are also the Serial1 serial port pins. The attachInterrupt() method sets the function that executes whenever an external interrupt is generated, and the detachInterrupt() method clears the function used to attend a specific interrupt.
Syntax |  |
    detachInterrupt(interrupt)
Parameters |  |
interrupt |  | The number of the external interrupt, from 0 to 7
Returns |  | None
