Hi all, I'm looking to create an electronic candle and need some help. First of all I want to use a group of LED'S for the light and vary the output in a RANDOM manner to create a shimmering effect of varying output similar to that of a candle. I would like the output variable so that I may control the apparent brightness of the "candle" to any where from almost full on to full off. Can anyone give me some ideas on where to start?
