Thanks, Quaralane.
Thanks, Constantine.
I had a short circuit with the chip and now 6 of the LEDs are flickering randomly. I have to order another board and and this time I need to be careful of the stray wires.
I really want to learn how to use an Arduino to control the lights and play sounds, and be able to control it all from my iphone. It can be done, but it will significantly increase the build time. And I have to learn how to program in the Arduino programming language. And since I have a 6 week old son, none of that is doable.
