Lastest milestone on the completion of our team installation, aFLOAT, for the MIT+150 FAST festival. This is a proof-of-concept for the multiplexing and animation code in the installation. It’s run off of an Arduino and a series of TLC5940 multiplexing chips – we tried conventional multiplexing but had issues with flickering when we tried to dim the bulbs (not to mention overloading the Arduino itself). The animation is triggered by a piezo sensor at the upper left corner of the matrix. This version has 64 LEDs (8×8) on a 4″x8″ breadboard. The final product will be 150 LEDs in a 12′ diameter circle!
