Problems:
- Arduino resets on serial open() from bifferboard (including explicit disabling of DTS)
- Arduino flashes digital outputs high on reset
- Digital output flashing high triggers door open
To try:
- Physical reset button on arduino (see if it flashes digital pins)
- 120 ohm resistor between 5V and RSET on arduino
- Replace diode on solenoid
- Use a capacitor to smooth over the reset pulse, requiring > 1 second to trigger relay
- Rebuild transistor/relay board
- Use a solid state relay (no transistor required)
