Well, I've searched the forum and found various hints at how to fade LED's such as using a quad op amp, an oscilator, pulse-width modulation/dac/analog ramp. But none of the threads have actual examples of how to use any of these techniques. PWM seems like the one recommended the most, but I could not find any specifics on PWM or pulse-width, and the closest on the main site was this chapter on PWM power controllers.
My project is to make a nightlight for my daughter's room from an old toy that recently broke. It's one of those fiber-optic toys with the bundled epoxied cap on one end, and the loose fillaments on the other that spread out in a big dome-shaped cascade of the fillaments.
I've already modded a project box that it can slide into just fine, and works with some blinking LED circuits I've made, but would like to fade the LED's slowly in and out at different intervals for each color. Currently I have 6 leds (red, yellow, orange, blue, green, pink).
What would be the easiest route for my particular project?
