I need to illuminate a led very slowly and smoothly, as part of a voltage controlled filter. I suppose I'm looking for a sine wave and there are better alternatives than the 555 but wondered what's the closest to a sine wave that could be obtained with a 555.
I can get a very smooth transition with a two transistor flip flop but I can't seem to get a smooth on and a smooth off at the same time, plus there's a dead zone between flip and flop.
Any suggestions appreciated.
