First of all I don't have much experience in fabrication and circuits. I can wire leds and resistors no problem, but that's about it.
I'm trying to put together a mechanism that will slide an object forward, stop and turn off, then reverse, stop and turn off. The plan is to use a DC motor and a DPDT switch, the problems I am having is the mechanism will be out of my view (can't tell when it is in the desired position) and what size of motor needed for this.
The motor will be powered by 12v (car battery) and will only need to push/pull max 3lbs. (I would like to go as cheap as possible)
What would be the simplest way to turn off the motor once it reaches the desired position?
I can only think of using microswitches at each ends that will turn on leds, then manually turn the switch off... is there a way to automatically turn the motor off?
Thank you in advance and I apologize if me trying to explain this is confusing.
