PROGRAMACIÓN DE SISTEMAS EMBEBIDOS CON ARDUINO: Laboratorio 7: 4 pulsadores controlando 1 triangulo en Processing

4 PULSADORES CONTROLANDO 1 TRIANGULO EN PROCESSING:

El laboratorio número 7 consiste en mover un triangulo en processing con cuatro pulsadores que controlan cada punto cardinal.

// constants won't change. They're used here to 
// set pin numbers:

const int buttonPin4 = 4;     // the number of the pushbutton pin

const int ledPin =  13;      // the number of the LED pin

// variables will change:
int buttonState2 = 0;         // variable for reading the pushbutton status
int buttonState3 = 0;         // variable for reading the pushbutton status
