Fading LED using 555 timer
This circuit uses a 555 timer as a clock pulse. Using the discharge of the resistors and the capacitor causes the LED to fade in and out. You can of course use any resisters or capacitors you want to adjust your preferred timing but in this circuit I use a 10uf capacitor and a 100k resistor.
