I am adapting my Arduino Uno to test old strands of WS2811 pixel lights. These are 12v strands with a data line. I am planning on power injecting the pixels with my 12v power supply. So I will only provide output from my Arduino to the data line of the strand.
I have quite a few strands so I am thinking of using my 74HC595 module so I can test several strands.
My goal is not to create a sequencer but just a simple tester. Turning on a single pixel for a brief second or two and then move on. Eventually, I would like to add a button to speed the cycle up/down as well as a pause when I discover a problem. And maybe increase the single light to 2 up to 5.
Any help would be most appreciated.
