You can make this little yet interesting project,it's simple and easy to make.
Step 1: Led on AC Power
Gather items to build this project
1) one red led
2) 68 ohm resistor for red color led (voltages may vary for different led's).
3) soldering iron and soldering wire
4) two wires
Step 2: Solder Time
Now, take 68 ohm resistor and solder one end of resistor to the positive terminal of led.
Then,solder negative terminal of led to a wire.Take another wire solder it to remaining side of the resistor.
Peel the wires and you are ready to glow your led.
