Door control system/Logbook

Problem:

• 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)

Problem:

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

To try:

• Replace with header/plugs
