What you'll need for this chapter
You'll need your microcontroller, a USB cable, and computer. You'll also need an ADXL345I2C Accelerometer such as the Adafruit Industries product ID 1231 or the SparkFun product ID SEN-09836, and an LED matrix kit from SparkFun—product number DEV-11861. You'll also need your LCD display from Chapter 4, Using Specialized Output Devices. Finally, you'll need a USB gamepad—I recommend the N64RetroLink controller that is available for about $15 on Amazon, but if you have a spare PS3DualShock 3 controller, I will also include instructions for that.
