This Processing sketch sends the same bytes as the Xport that’s configured for the networked Pong game in Chapter 5. It’s a handy way to connect a microcontroller to the server when you don’t have an Xport, or aren’t sure your Xport is working.
/* Analog output Language: Wiring/Arduino Reads an analog input and uses its value to dim an LED output Connections: analog sensor on analog input pins 0 LED on digital pin 3 */
This program reads two analog sensors and one digital sensor and prints them out. Use it for testing your sensors.
This program reads a switch (i.e. a digital input) and changes an LED only when the switch changes from off to on. You can modify it to count switch presses as well. There’s a digital input connected to Digital I/O pin 2, and an LED attached to digital I/O pin 3. I refer to this method of detecting when the switch has changed as edge detection on a switch
/* pong server Language: Processing
version 0002 This program listens for TCP socket connections and uses the data from the incoming connections in a networked multiplayer version of pong.
Version 2 fixes a bug with the delayCounter. NEw lines are shown in bold below.
