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

Setting up a Bluetooth Mate

Here we have a quick tip type post detailing how to configure a spartkfun Bluetooth Mate for micro-controller based serial communication. To this end I will detail how to change both the Baudrate (bits per secondĀ for serial data transmission) and the name of such a modem. Once you understand the basic method needed for communicating with these devices, you will be able individually customise them to match the bespoke needs of your project; including features such as setting the devices password and enabling and disabling authentication. ...more
