New low-profile electronics

So the Raspberry Pi Pico could not handle the flow of interrupts. So it is back to Arduino.

Also, I realized that I can make the electronics slimmer if I solder the pins and remove the plastic bar. So this is basically back to what this looked like long back.

But it is modular now and that will be such a relief. Motors work, but the encoder is misbehaving. Will have to figure that out.
