2021-11-26 (F) Weekly Summary

I mounted all the buttons and the screen to the front of my faceplate. I went with silver bolts in black plastic and black screws in white plastic. I don't like the empty holes in the top of the switch arrays, but it's not worth the trouble to fix.
All the operators on my drum machine

Now that everything was mounted, I began wiring. With twenty-five operators, there were a lot of conductors to track. I used the same order for the wires on each switch array to keep things neat.
Faceplate backside

I decided it would be easiest to attach my wires to the most convenient location and sort it out in software. The ones I connected earlier were intentionally long, so I trimmed them to the correct length and soldered them neatly in place.
Wiring on protoboard and faceplate

I had a couple of prototyping boards in my stock, but I opted for one with no headers, so I soldered my own and added one resistor for each switch input. My soldering iron was also giving out, and that was frustrating.
Fixes need on my IO list

I connected the Arduino to the computer and started the function to check all my inputs. Most of them worked, but a few were problematic, and I reconsidered my earlier decision to use some of the data ports as switches.
Relatively neat wiring

I moved my switches to GPIO and cleared off the serial pins. The process was a lot harder than the first time because I had to hold wires in place while holding the whole board while holding a soldering iron while holding solder. It was not fun.
Microseconds between button press and release
