In this video I will show you how to connect multiple 'Light Emitting Diodes" in series without the use of any resistor on a breadboard.

If your LEDs dont light up here are a couple troubleshooting problems that you may have :-
1) 1 or more of the LEDs are facing the wrong way.
2) They light up but are very dim - Not enough voltage or you could have the LED the wrong way.
