Paso 9: Añadir el código a tu Arduino.
Abra el software de Arduino IDE, suponiendo que usted ya ha descargado e instalado. (Usted puede obtener gratis desde: www.arduino.cc/en/Main/Software
Vaya a archivo > ejemplos > conceptos básicos > Desvanecer. La secuencia de comandos se incluye en la instalación, pero si no lo tiene, aquí es.
/* FadeThis example shows how to fade an LED on pin 9 using the analogWrite() function.This example code is in the public domain. */int led = 9; // the pin that the LED is attached to int brightness = 0; // how bright the LED is int fadeAmount = 5; // how many points to fade the LED by// the setup routine runs once when you press reset: void setup() { // declare pin 9 to be an output: pinMode(led, OUTPUT); }// the loop routine runs over and over again forever: void loop() { // set the brightness of pin 9: analogWrite(led, brightness);// change the brightness for next time through the loop: brightness = brightness + fadeAmount;// reverse the direction of the fading at the ends of the fade: if (brightness == 0 || brightness == 255) { fadeAmount = -fadeAmount ; } // wait for 30 milliseconds to see the dimming effect delay(30); }Ahora sube el código a la placa.
