I have built a small macro keyboard with an Arduino pro micro and some cherry mx switches, but for some reason, I am getting no response out of it. The keys do not provide an input when pressed, and sometimes I will receive inputs when nothing is being pressed. This was my first time soldering anything, and it was a bit messy, but I am fairly certain I soldered everything correctly. Also I feel kind of stupid saying this but, I have not built a case/stand for the keyboard, so I am just testing it barebones, with the PCB exposed (Image here), so maybe its possible I damaged it some way? Also, could my USB cord be the issue? I am using a micro USB, and it does fine to communicate with the Arduino and upload sketches, but could it be blocking my key inputs?
Anyway, here is the code I used to test it
Also here is the tutorial I tried to follow while making it
Thanks, and sorry for the super long post
