I tried to get my phone to recognize the hidkeyboard.ino example, but I did not have any luck. I dug into a second keyboard tutorial from Adafruit which used six keys, whereas I have 75. I had to tweak the code to send keys periodically since I could not trigger them with inputs. The phone still refused to acknowledge any letters, but my computer responded, so I continued.

I programmed the bottom row, which was a tricky place to start since most of the modifier keys were there. Modifier keys are shift, alt, ctrl, and GUI (Windows button). I found a document that listed the button codes, but it did not help, so I played around with the example sketch until I figured out how to send them.

In the second row, I hit another snag because I put three volume keys there, but the computer would not recognize them. I replaced them with unique function keys, F13, F14, and F15, so I can use AutoHotkey to change the volume.

The third, fourth, and fifth rows went smoothly, but I had to research the button with the tilde to figure out that it was also called "grave." My escape key also releases all buttons so I do not get anything stuck. I tested the layout with an online utility. There was a loose solder joint on my equal key, but I will fix it, and I could not test the function keys where my volume control should be. When I retested with my phone, it worked!
White keys worked
