I revised the schematic to include the build changes. I remembered the I2C pin numbers this time, which I had to look up again. I only spent a little time on the revision since there were minimal changes, but I wanted to include an updated picture.
Updated left-hand schematic
I connected the two keyboard halves with a TRRS headphone cable, then added code to print any data from the right-hand side. I did not see anything but found an error in the code of my left-hand keyboard where I did not initialize the port. I still had no data, so I connected an LED to the data lines. When I reduced the baud rate to 9600 bps, I detected the flicker with my bare eyes, so I knew the right-hand keyboard was transmitting.
I connected the right-hand keyboard to a different computer to edit simultaneously but could not get the Arduino IDE to upload code. I updated, then downgraded to <2.0.0, but I still struggled. Eventually, I realized that I had the wrong board selected. There were missing keypresses, which was laggy, but when I reduced the serial speed, I had better results.
