Mydooropener is not opening the garage door. I get the status. I have checked configuration several times and it should work. One posible cause for it for not to work is that I set up inversed polarity for a few seconds (20/30s) until I realized that the board was getting warm . I changed polarity and leds turned on.
My question is how can I know if my circuitery got damaged? When I power it up a see a few leds including "led 4" which I assume it belongs to rele 4. Leds for reles 1, 2 and 3 do not ever light up. Does this mean anything?
Some more info: If I configure door to be opened from rele 4, it gets opened as soon as I power up the arduino.
