    Hey guys im doing a school project and need your help on the electronics side. I just dont get any of it [​IMG]

    Basically, i'm making a plane which tilts left and right (to emulate air flight). The circuit will drive a motor, which turns some gears, which then pulls down a hook. There are two of these mechanisms on both sides. this is what i need help with:

    1. The switch is pressed
    2. motor spins for 1. - left wing moves down
    3. motor spins for 2. - left wing moves up, right wing moves down
    4. this is repeared until button is stopped
    5. there is a 5 second time difference between the movements

    I have no idea how I could go about doing this. I need to use these components:

    555 astable timer
    pulley hook thing

    Im using the normal components such as resistors etc etc

    Here is a pic of what im trying to do:

    do i neeed to start the plane on a tilt?
    Any help will b appreicated so much, basically i need help making the circuit diagram! Thanks all!!

    I'm going to move this to homework help. The motion is easier if you simply pivot the fuselage. One motor can pull or push against a spring or weight, making your project easier to construct.
