So, you've blinked some LEDs with Arduino, and maybe you've even drawn some pretty pictures with Processing - what's next? At this point you may be thinking, 'I wonder if there's a way to get Arduino and Processing to communicate to each other?'. Well, guess what - there is! - and this tutorial is going to show you how.

In this tutorial we will learn:

  • How to send data from Arduino to Processing over the serial port
  • How to receive data from Arduino in Processing
  • How to send data from Processing to Arduino
  • How to receive data from Processing in Arduino
  • How to write a serial 'handshake' between Arduino and Processing to control data flow
  • How to make a 'Pong' game that uses analog sensors to control the paddles

Before we get started, there are a few things you should be certain you're familiar with to get the most out of this tutorial:
