The Digikey order I was waiting for finally arrived, so I spent yesterday evening assembling the front panel for the rhythm-robot. I got three of the encoders and four of the lighted push-buttons wired up to a pair of I/O expander chips; it’s a surprisingly laborious process, as I am using bare perfboard, so I have to cut and solder jumpers for every connection. It’s ok for a prototype, but I’m definitely going to get boards printed if I ever make another one of these.
