Simple Bluetooth Joystick

In this post I will introduce a couple of Arduino scripts and the accompanying circuitry needed to make a very simple Bluetooth joystick. The first script simply provides you with all the basic code needed to read from a simple PS2 style joystick. This script is then expanded to include the capability for joystick calibration. Calculated calibration values are saved to the micro-controllers EEPROM so that they can be automatically retrieved next time the hardware is connected. ...more
