Thanks for the great project. I built the keyboard module, but I’m having trouble getting it up and running. When I plug it into my Windows PC, it looks like it attempts the startup animation, but then the right most led in the bottom strip stays on bright white. What does this mean and how do I troubleshoot it?
When I took a peek at the program, I noticed there appears to be a debug mode that is currently set to false. Can you provide a little tutorial on debugging?

Hmm, weird. Does any of the other LEDs show the start-up animation?
1. Do you have the right version of the pro micro (5V 16MHz)?
2. Doublecheck the orientation of the led strips. (the Data IN should be connected to the Arduino).
3. Set debug to true, recompile and upload. Open a terminal (@115200 baud) and check if you see debug info when pressing keys.

Thanks for the reply. I think I have the right version of the pro micro. I’m using this from Amazon: https://www.amazon.com/gp/product/B08THVMQ46
I double checked the orientation of the led strips. Data in is going to the arduino.
I get lights at start up, but they look weak. Then the right-most LED stays on bright white and won’t turn off.
I’m wondering if the wire I used was too small. I used some strands from some old speaker wire that I had, but they only measure about 0.1 mm rather than the 0.3 mm that you suggest. I may need to start from scratch and find some larger wire.

Well…I was double-checking some of my soldering joints. It looks like this was my problem. I had a very difficult time with soldering all those switches without melting the surrounding PLA. My soldering skills are not the best. I tried to clean up the solder joints, but in some cases the PLA plastic has melted to cover the switch post. I may start over and try from scratch with a second board. Hopefully my soldering skills will improve.

That could explain it, but also the thin wire, especially for power and ground.
Try to be quick with the soldering. If you just solder the wire and component, the plastic won’t melt.
Practice makes perfect ;)
