i think the circuit would command a motor both directions.(open/close) and can stop it.
( using relay ... )
i am looking forward to hear from you .
Thank you

Don't forget to code the safety system, so it stops and reverses if the door hits something. Like a person.

Decide on the actuator first there are various options depending on the type of garage door. That will allow you to design the interface.

For something like this you need to take safety seriously. Limit switches to detect/prevent overun, and as previously stated a method of detecting obstacles.

I'd suggest measuring excess power consumption in the actuator if electric, and excess pressure if hydraulic.

Hello,

Thank you very much for reply.

but i don't have any idea how to do that.
the kind of garage is like on picture that go up and down.
with electric motor.

do you have any link or something where i can find the circuit ?

Hamza, without more details photos and existing circuit diagrams, or at least model nos. how can anyone advise you?

You say the door is already controlled electrically - what exactly are you attempting to do?

Hello Dave,,
no there is no door,, i want to make the circuit that can controlled by a remote.
the circuit should open / close / Stop the garage.
i am not talking about motor that will make action.
--   ( maybe like this one but with remote not laser )

remote  sensor receives the signals then the microcontroller will send command to relay driver IC the contacts of which are used to switch on the motor used for opening the garage door and it will switch off the motor after predetermined time.

help with what?  you haven't asked a specific question, you've asked us to design your entire project.

you want to create a door controller.  you are asking for help creating a door controller.  that is too broad of a topic to get specific help with.

break it down into smaller problems, and solve each of them in turn:
  • Create a motor controller that can drive the motor in the existing unit, or control the motor via the existing control circuitry.
  • Read input from sensors to know when the door is fully open, fully closed, and if there is an obstacle that would prevent door closure.  Don't rely on timing, because it won't always take the same amount of time to open & close.
  • Listen for signals from the remote control.
  • Get a microcontroller to operate the motor controller, write the required software to read the signal from the remote and read the sensors.
  • Test it all, fix anything that doesn't work.
  • Done.

Minus any stupid errors on my part, that's probably how you're going to want to approach the problem.  That's more or less how software projects are done, anyway; one piece at a time.
