I have recently built a chicken house door opener using a picaxe 08M2 and various other components including an L9110H motor driver driving a simple gearbox motor to open the door depending on light levels etc. The system has worked flawlessly for about a month until today when I checked on it and the motor had not activated and was just making a pulsing clicking noise while stationary. I have a capacitor across the motor terminal as it would created too much noise otherwise. I just wondered if anyone could help as I am stuck as to why motor has suddenly stopped working. Is it creating noise that is going back to the picaxe and disturbing it? Is there any way to easily combat noise or it it best to find a new motor. When I disconnected the motor, the output was fine and ibtested it with an led and multimeter but with the motor connected the led just pulsated and the meter didn't register any DC voltage. Thanks
