Problem (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)

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:

  • Chocolate block "plug" is loose, sometimes causing loss of power at slightest touch

To try:

  • Replace with header/plugs


Problem:

  • Flashing arduino has stopped working (stk500v1: no response)

To try:

  • Another arduinio
