As an exercise in basic EE and basic maths, i want to fade out a LED with a capasitor. I wonder if anybody could peer-review my calculations? [LED fading with a capasitor] Given i am using a 10k? resistor and a standard LED in series, and in parellel with a 100µF cap, all in a 5V circu…

Basic maths: 10k? resistor, 5V voltage, 100µF cap=0.76 second LED fadeout

How come you're not using a transistor ? You can make it fade out nicely then!
