    Hey guys,:D

    I need to make a Power ON Delay Circuit with variable delay from 1sec to 10sec using 555 and a pot(variable resistor).
    That is when power is given to the circuit it must not produce an output until the delay time(say 1sec to 10sec).
    Providing a schematic diagram with time delay equation will be sufficient.
    Thank you.........:)
    Its Very Urgent.........

    Hey Bill,what's the value for the other Resistors and capacitors...?
    In the T=1.1RC equation,R in ohms and C in farads or microfards.......?
    pls reply.
    i'm looking forward to your circuit......
