    Can someone tell me how to make a timer that would be used to automatically turn lights on and off. Thank you.

    How many minutes you want the timer to delay the lamps from lighting and how many minutes you want the lamps to be on before they go off?

    Is your project for low voltage lighting (like under 15V) or for 115/230V?

    If the latter, I strongly suggest that you simply purchase a commercially available timer. They are inexpensive, reliable and safe, something that a home-built timer may lack on all counts.

    Buy a cheap one at the Walmart would be easiest. Bribing a sibling might be cheaper but more erratic. ;)

    if your circuit is a low powered one then use a 555 I.C. as a monostable
