I am attempting to make a motorised camera dolly which reverses direction at each end of a dolly track
It will be a carriage driven by a 9v battery powered electric motor
I need to make a small circuit to automatically reverse the polarity to the motor at each extremity of travel, so that the dolly changes direction
I have read that this can be achieved by the use of a reed switch mounted to the carriage, and a magnet laid at each extremity of travel
Can anyone suggest a simple circuit to achieve this?
