LED (Light Emitting Diode)

LEDs are small electronic device that emit light when an electric
current passes through them.

LEDs have two leads (terminal): the longer lead is the positive
(anode) and the shorter lead is the negative (cathode).

LED comes in various colours.

Resistor

A resistor is an electrical component that limits the flow of current in a circuit.
