    Ok here it is....I have a project in for Thursday, ive been tearing my hair out for weeks trying to get this to work. My problem is:

    Button 1 + 3 moves motor A clockwise.

    Button 2 + 4 moves motors A + B clockwise.

    Motors latch, it should be momentery, stop when button is let go

    It is supposed to:

    The buttons should be momentary
    Button 1 should move motor A one way
    Button 2 should move motor A the other
    Button 3 move motor B one way
    Button 4 move motor B the other
    And be momentary.

    Are my positive wires position causing the problem?

    Will

    You've told us what is supposed to happen, but not what actually happens.

    As far as I can see you've implemented an H-Bridge using relays (which incidentally is exactly what my garage door opener uses).

    Have you tested that your IR remote can transmit signals for 2 buttons pressed at the same time?

    Is this your homework? Have you left it too late?

    Why do you want to use 2 buttons when 1 would seem to suffice?

    Relay 1 and 3 make sense. Are relay 2 and 4 for a second motor?

    It is degree c/w. The intended result was:

    Switch 1 rotates motor A left
    Switch 2 rotates motor A Right
    Switch 3 rotates motor B left
    Switch 4 rotates motor B Right

    It is to opperate a household spotlamp to aim to any point in the room.

    what actually happens is:

    Switch 1 rotates motor A left
    Switch 2 rotates motor A + B left
    Switch 3 rotates motor B left
    Switch 4 rotates motor A + Bleft.

    Im not sure if the positive off the relay is going to the correct point. It has to got to a positvie so I stuck it to the closet 6v
