How to control a tiny motor with a garage door opener or keyless entry remote?

[bruce1129]

Anyone know how to control a tiny motor with a garage door opener or keyless entry remote. tiny motor would need to be battery operated, a motor in a mini RC car is what i have in mind. I only need it to move one direction. There was a post on here previously that I didn't understand. I know very little about this subject.
ANY helpers would be greatly appreciated

Re: Garage Door Opener

hi,
u can move a motor with controlling its motion in even two directions, using

1. motor
2. window comparator
3. Variable Resistor
4. Opto Coupler (4N25 OR 4N35)
5. Relay (Contactor)

just go through window comparator (using OP-AMP), u will then be able to do it.
