I worked with Matt Richard for midterm assignment of living art class. We tried to create some patterns with LED’s in tubes on white surface. Soldering bunch of LED’s was very painfull. We used TLC 5490 to multiply the LED’s each TLC can be used with 16 LED’s also you can daisy chain them up to 9 TLC. We used 4 of them, which means 64 LED’s.  TLC5490 gives you full control of each LED.

Wiring of LED’s also looks very intense:

Also we have a video with the lights
