Finally got round to changing my loft door over to reed switch from hall effect sensors. Open and close switches to prevent closing too far or opening too much and killing the motor/winder.
Whilst I was doing it I killed the original arduino, lovely smell of something electronic going pop. I had stupidly soldered the nano directly to the board meaning I couldn't swap it out easily. Tried to unsolder it but it wasn't budging. Ended up making a new board and added female socket headers so I can swap it out and reprogram without disconnecting the whole board.
