INTRODUCTION

Competition for motion controls include:
Microsoft Kinect
 Sony Move
 Nintendo Wii

Many games released are not top selling or rated
games
 By creating an open source platform with
hardware and software, gamers with a vast range
in technical knowledge can have a resource to
review and expand controls to play their favorite
games with any motion control they wish.

OBJECTIVES
Develop an interface between a microcontroller
and an Xbox 360 Controller
 Allow the microcontroller to accept various
inputs through different mediums
 Interpret signals and convert to acceptable
outputs for the Xbox 360 Controller

CONCEPT
Provide the minimal hardware to interface an
Xbox 360 controller to a microcontroller.
 Establish a preconfigured serial connection
with a computer.
 Sensors for control can be

 Directly
connected to the microcontroller
 Sent over computer via
 USB
 Bluetooth
PURPOSE




If you can program your
own games, why can’t
you build your own
controller?
Customizable control
scheme for any game
Add motion controls
 Interact more with a
game


An appealing project for
future students
