    hye..can someone help me how to design a circuit in which when we switch on the circuit,it do not immediately start then it will start after 5 sec and then it will stop back after 15-30 seconds after it moves..

    What do you wanna use ?

    A 555 timer or a μC ?

    use a 555/6 timer circuit like this , alter the resistor values to suit your delays..

    After what moves? Is the automatic stop to happen 15-20 seconds after something is powered on or after an event occurs (something moving)?

    Will this do it for you?

    Edit: This needs a latch, but if the OP never comes back, or his circuit is nothing like this, I won't spend the time to make one.

    What motor? Does it, by some miracle of luck, use 5 volts and only a few milliamps? If it does, attach it to the line that says, "high = on". If not, add an amplifier to the line marked, "high = on" so the amplifier can drive the motor.

    Did you just say you want to change the circuit now?
