Wireless gamepad case
This is an arduino based gamepad designed for use with RetroPie on a Raspberry Pi. The Gamepad uses a bluetooth connection to the Raspberry Pi.
Source code for the Arduino and a driver for the Raspberry Pi are at https://github.com/batemanm/gamepad
Note - the position of the buttons is for an 8 year old's hands you will probably want to change it for an adult.
