/DIY/, I am stumped.
I'm building a giant LED Matrix (Pictured). However, I was having issues with several rows turning off and on - Usually all at the same time. I figured, a loose power wire. The structure is simple - 8 shift registers, which sink to ground. So, every LED is connected to a +3.5v power supply. All the data, etc are connected together, and to an arduino.
