Could anyone give me a circuit diagram? I plan to use a 40 or 60 W bulb with 240 AC mains as supply. The type of flickering I need isn't "random" or anything, I just need the bulb to go on and then become dim, again on and then dim. I would prefer something like this: 500 ms on, 100 ms dim and repeating. I could easily use IC 555 to give the required duty cycle, IF I had something like but IC 555, but right now I can't because it doesn't work on 240 AC and I need to use a bulb which works in 240 AC. What would be the simplest circuitry to do this? I don't have knowledge too much of programming 8051 and even if I did get the program, I don't know how exactly to feed that program into the micrcontroller.
Would there be a problem (like to the bulb, or the tungsten filament in the bulb) if a 40/60W bulb working with 240 AC flickers?
