Vending Machine for Birds (OLD)

v1.2 PCB tests ok.

v1.2 PCB gerbers and bom uploaded

I've finished the v1.2 PCB and ordered it. I'll upload the new Gerber's shortly.

After some testing I found two issues that I will solve in an update at the start of June. 1. C7 needs a bleeder resistor in parallel so the dispense trigger works repeatedly. 2. The timer needs to enable the IR sensors when triggeting the motor so the dispense sensor can stop the motor after it has dispensed a peanut. Else it will dispense ~10 or so when the timer triggers it. Other upcoming changes - removing motor and timer monitoring pins from the header - PIR, IR, dispense and deposit are more critical - changing the pinout of the external header so it fits with common 4-channel level shifters (so you can monitor and control it with a 3.3V device like an ESP-CAM) - some optional capacitors for dampening power-on signals that the phototrasistors give out when powering up.
