In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.

This instructable will guide how to use LEDs and how to make simple basic LED circuits, which current limiting resistor to use for operating LEDs with 3V, 6V, 9V & 12V.

An LED or light emitting diode is a semiconductor device that emits light. LED lighting is starting to replace incandescent, fluorescent and other forms of lighting in homes and other buildings. The color of light the LED emits depends on the material the LED is made of. The cathode of an LED is the negative side and the anode is the positive side.
