led timer circuit
I am looking for a timer circuit diagram that would light up 10 leds in a random manner, and the time delay interval could be adjusted....say from 1 to 15 minutes or so. For example, once power is applied, 4 leds would turn on, then a few minutes later a number of other leds would turn on while others turn off. A variable pot. could be adjusted to vary the on/off intervals. Thanks for any assistance.

It sounds like you will need a PIC or other micro controller. You will probably use up/down switch or a nob that generates this function (up tick down ticks).
