### analogWrite()

Examples |
    import processing.serial.*; //Import the Serial i/o and the Wiring Libraries
    import Wiring.*;
    Wiring wiring; //Create a Wiring object

    int outpin = 29;
    int val = 0;

    void setup() {
      println(Wiring.list()); //print the serial devices list
      //inicialized the wiring object
      wiring = new Wiring ( this, Wiring.list()[1], 57600);
    }

    void draw() {
      Wiring.analogWrite(outpin, val); // sets the value of PWM pin 29
      val = (val + 10) % 1023; // increment value and keep it in
      // the 0-1023 range.
      println(val);
    }
Description | The analogWrite() method sets the value of a PWM output pin. Possible values range from 0 to 1023. The analogWrite() command works on PWM output pins 29, 30, 31, 35, 36 and 37 only.
Syntax |
