I recently built two pads… the keyboard I made worked right away. The pads I have checked everything over twice and it is wired correctly. The only thing that is out of the normal is that the Pro Micro boards I received are showing up as a leonardo bootloader. I am new the arduino world so I am not sure if that matters or not… I tried flashing it multiple ways and get no lights on the LEDs. I just get the Arduino to power with a constant red light and one flash buy pin 7… not sure what I am missing :( It was some of my best solder work haha so I would had to junk the thing…

Strange. I just downloaded the code and it works as expected.
Here are some questions that helps narrow down the source of error:
- Were you able to upload the program (double check that you use the right version)
- Do you see the LED animation at start?
- Does the right red led flash when you press any of the eight pad keys?
The leonardo boot-loader should not cause any problem.

I appreciate the response. And I apologize for anything stupid that I may have messed up. I am a total beginner and was excited to have the keyboard working and wanted to make them all to learn.
- I was able to upload just fine. History: 2020-11-03 that was the script I pushed with no errors.
2. No LED animation at startup. no flashes at all.
- Nothing happens when I press any buttons. This is on both pads that I have made. i just get a red light on the board and a single flash near pin 7
Hopefully, this give you the information to narrow down what I have done wrong. Glad to hear the leonard boot loader is fine because I have 4 of these boards :)

Then I would focus on the lower LED-strip.
- Check that it is oriented correctly (signal in / DI to the right and GND on the bottom.
- Measure connection between DI on the LED-strip pad and pin2 on the arduino. (using continuity tester on a voltmeter)
- Measure connection between +5v on the LED-strip and VCCon the arduino
- Measure connection between GND on the LED-strip and GND on the arduino
You can also connect it to a computer with a DAW software running (handling the midi events), then the tx led should flash for every key press. (Verify this behaviour first using the working midi keyboard)
