how can i get a 12v motor to automatically reverse polarity or direction either by a certain time or by ???
I have a machine that is for hunting that swims duck decoys back and forth. See youtube video " home made wake maker " but right now i have to swith the direction automatically and i need something that i can just turn on and let the decoys swim back and forth without me touching anything. Anyone have any suggestions? The motor is a 12v trolling motor with simple pulley on the top and wires are ran all the way to a box where i have a on and off swith and a switch that reverses the polarity!
