Posted March 31, 2014 by Chris
"When I learned about Elco Jacobs’ amazing ShiftPWM Arduino Library, I knew all I needed was a little general purpose driver board to light all that LEDs up. the library basically uses shift registers and a high frequency serial signal in order to PWM control a lot of LEDs on just three Arduino pins. handy enough, I was introduced into etching PCBs at the same time, so there it was, my first etching project."
