I am wanting to build an automatic feeder for some of my farm animals. What I have in mind is using a car seat electric motor which haas a forward and a reverse. Next I would like to use a digital timer like used on deer feeders to operate the car seat motor. At a specific time the motor would turn 'out' to present the feeder bowl to the animal and at a specific time the motor would turn on to 'pull' the feeder bowl back under a barrell to be refilled. The problem is the digitial deer feeder timer only has one wire to the motor. Is it possible to use the deer feeder digital timer and if so how could I use it. Or are there 12 v timers that have multiple timers where one could be hooked up to the motor to make it go forward and one to make the motor go backwards. Sorry for the non-technical terms !! Thanx.
