This guide will show you how to turn your Arduino Uno into a Windows/PS3 controller. It is fully configurable and you can change the input/output to whatever button you want. This means that you can hook a wii nunchuck up to it and play around with the coding a bit until it works. Really you can hook any type of sensor or whatever you want to it as long as you have enough inputs and outputs.
Step 1: Whats Required
The only items that are required are:
*Arduino Uno(Untested on other models but still might work) *A way to connect your Arduino to a Windows computer *A Windows Computer *A way to ground the DFU mode pins as seen in picture
