Problem 1 (identified by solexious at the weekend):
- Arduino resets on serial open() from bifferboard
- Arduino flashes digital outputs high on reset
- Digital output flashing high triggers door open
Tried:
- Disabling DTS (didn't work)
Workaround:
- Open serial port on boot
- Hope it doesn't restart
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)
Problem 2:
- Chocolate block "plug" is loose, sometimes causing loss of power at slightest touch
To try:
- Replace with header/plugs
Problem 3:
- Flashing arduino has stopped working (stk500v1: no response)
To try:
- Another arduinio
Problem 4:
- Rootfs went away at 4:04am
