Synchra Project - Lots of RGB LED Arcade Buttons

A test of eight RGB LED Buttons.

It's driven with two TLC5941s, 16-Channel PWM LED sink ICs and a Arduino Uno. I have to say I love these chips:

• 4,096 levels of PWM
• 16-Channels per chip (5 RGB LEDs)
• Only one resistor for all 16 channels

The only drawback is that their on the pricey side at $4.45 ea.
