I recently bought a replacement kit to build (I dropped something on my first pre-built kit and broke it ) and I have built it and had some issues with it. Boy, that is a lot of solder connections to make.
Anyway, I have been able to debug all of my problems (and fix them ) but 2 and I was wondering if I posted a picture, some code, and a description if someone might be able to help me figure out what is wrong. I have looked at the Eagle files of the circuit boards, traced paths with an ohm meter, and can’t for the life of me figure out what is going on. I wish I had one of the 8*8 led matrix’s to plug into my rainbowduino to test it, but I don’t. I am wondering if the problem could be there.
Briefly, I have 2 led’s that don’t light correctly. Green works on both of them. One of them will not light red, and the other won’t light blue. The led’s are mounted in the correct orientation. I also replaced one of them and still no go and the one I took out lights fine all 3 colors on my bench. My logic (and ohm meter) tells me that all of the traces are good because other led’s that connect to the same pins are lighting, and the common traces are good because they light other colors on these 2 led’s.
So should I post a picture, which xyz coordinates they are, my code, or what.
Thanks in advance for your help, John.
