    That should do. As for motor size, that will depend on how much friction there is in your mechanism and on how fast you want the door to move. Even a tiny motor could move the door (albeit slowly) if it's geared down enough.

    1. You should have a track, and 2 ball bearings (20mm will be fine) spaced to equally distribute load.
    2. Using the weight of the door and other neecessary equations, you can calculate the force required to move the door left to right, which will also be right to left.
    3. Getting the force is necessary in order to properly select a motor. From force calculate torque requirements for a few motors to get the suitable motor, couple this with your gear mechanism ofcourse.


    Btw, i feel an easy way would be to rip the chain of an old bicycle and the sproket, fix sproket on motor, and lay chain out flat on door. Braze the chain onto the door to avoid the pulling that comes with welding

    You also need to state how fast you want the door to move, and how far you want the door to move.

    Microcontroller will help you much, I suggest you to using it, put 2 button to controlled Left & Right.
    :confused:

    What's the door for?
    What's the power source?

    Why would you think you need a microcontroller, when all you need is a switch?

    Ucok (inappropriately) dug up a long-dead thread.

    Hi B.
    Sliding door you have to collect some sort of sensor to
    detect people approaching, with some sort of drive to operate the door. Collect
    some sorts of motor or actuator. Need basic knowledge on when the door is clear
    so you can close it again. And pressure pads each side of the door to sense
    people going throughout. I have done similar Electrical project before about
    POV Glove. That’s I had controlled control motor by using coding. :)
