A basic circuit:



             LED's (Light Emitting Diodes) are easily damaged if too much current flows through them. For this reason it is necessary to use a resistor to reduce the current flow. Note that LED's have a "+" and "-" lead, the "-" lead is beside a "notch" in the plastic base of the LED. If you connect an LED backwards it won't work. See "Sources" at the bottom for ideas on where you can get more information.
