A capacitor can directly fade an LED on and off as power is added to and removed from the circuit, such as by using a switch. This is not the most effective way to fade an LED but it's easy to make and easy to understand.

Thank you sir, i'm learning electronics and this was quite an educational video. I was using 5V DC and used a 10K resistor for the ultimate fade-in. So far i'm just tinkering with LED's, resistors, capacitors with switch. Next up i'm jumping into transistors. I've bought a lot of NPN and PNP transistors, LED's, zener diodes, photo-transistors and a stepper motor.
Good times!
Brooooooo! Thank YOU!
Thanks for watching!
hi sir, just curious please correct me if im wrong, is that really 3k ohms in the first resistor or 110 ohms? i see a brown brown black black yellow
color maybe im wrong?
The resistor is backwards when it comes to reading the color code. On the left is the tolerance and on the right is the first digit.
@@Electronzap ohhh ty for clarfction
Hi sir is it possible with 3v battery with this circuit ?
Some LEDs need 3 volts just to light up. Others light up at 2 volts. So, it likely won't work well with 3 volts.
What math is needed to figure out component sizing for controlling an LED strip? The resistors are easy but what about the capacitor? Like 12v 10 amp
