When I started this project, I chose to use inexpensive 12V light strips instead of 5V addressable lights. The cheap versions need a second power source, and they all have to be the same color. I didn't think we would need to change individual colors for this project, but I mostly wanted an excuse to see if I could control these lights with a 5V signal right from the controller.
I plugged in a 12V power supply, amplifier board, and lights to construct the circuit, then tied the ground connection to my controller's ground. When I connected three PWM pins to the amplifier, I could only get red to work. Blue and green would not light up or not at the correct levels, but I rearranged the connections until all colors were functional. For my test, I set all the lights to the same intensity based on incoming serial data, and when they all behaved accordingly, I knew I was using the right pins. The next step will be to change all three colors independently.
