Design and test electronics layout #26

The old design, here, uses a 9v supply and an arduino. However, we'll use a 5v supply with a pi zero. This means we don't need the voltage converter to get 5v.

[ ] draw new schematic as the old one isn't great (see here or here for free circuit drawing software)
[ ] check we can power on/off the dc 130 motors with the mosfet and 5v 2a power supply.

To test the servos, we will need a pi zero up and running with our python package installed.

I believe I did the original (now lost) circuit schematic with circuitlab.

The MOSFETs didn't work but the BJTs do seem to work just fine and still allow for low-side switching.
