Fading an LED on and off using a capacitor directly while switch by a 555 timer didn't work out as nicely as I thought it would. So in this video I improve the circuit by using a much lower value capacitor to control how much current a 2N3904 bipolar junction transistor (BJT) lets pass through the LED.
