If you want to create a colorful light show or a spiffy bicycle light, or just want to improve your electronic gadget skills, you will need to know how to hook up LEDs in a parallel circuit. Hooking up LEDs in parallel doesn't take much time, but you'll need to be careful: you don't want to supply too much current to the LEDs, or they'll burn out. Protecting your parallel LEDs require that you place a current-limiting resistor in series with each LED in your parallel circuit.
- 2 LEDs
- 2 1000-ohm resistors

1
Connect the cathode lead (the positive lead) of one LED (LED A) to one end of a 1000-ohm resistor (Resistor A).
-
2
Connect the cathode lead (the positive lead) of the other LED (LED B) to one end of another 1000-ohm resistor (Resistor B).

-
3
Connect the other ends of Resistor A and Resistor B.
-
4
Connect the anode lead (the negative lead) of LED A to the anode lead of LED B.
