Have you decided what you were doing with three LED's? Clumping them together? Perhaps one as a power indicator so you don't forget to turn the device off, one to light up when the time has elapsed. I will need to alter the circuit and perhaps the series limiting resistor depending on the use.wow....Thanks for all the input guys.
Time for some shopping now I think. Any good shops in the uk sell these parts...maplins?.....digikey?.....
