This is a gestural controlled LED matrix system. An accelerometer is built inside of a wrist band. As a user moves a hand wearing the band, the accelerometer detects the x and y position of the hand and changes the animations on the LED board. The LED board is an 8 x 8 matrix system with 64 LED’s, driven by four TLC 5940′s. More information and step by step instructions on how to make it is on Instructables.
This project was featured on Instructables. The code was written by Joe Laquite based on Arduino TLC5940 basic animation code. code

LED display, wrist band, and ArdulMU sensor board
I used TLC Arduino tutorial (http://www.arduino.cc/playground/Learning/TLC5940 ) to connect the circuit. The circuit is made with TLC 5940 LED driver, which allows you to fade LED’s as well as switching them on and off. Each driver can take up to 16 LED’s and can be chained with more TLC5940 drivers. This project uses 4 TCL 5940′s and 64 Superbright LED’s.
All the anodes on LED’s are connected to the power, and the cathodes are controlled by driver.
