A two-colour LED consists of two light-emit- ting diodes, usually red and green, encapsu- lated in the same case. It has three pins: two for the anodes, and one for the common cathode. In this way, each diode can be activated separately. Various colours may be obtained by varying the current through one or both of the diodes. For example, four colours may be obtained when the currents. are arranged as follows: red, green, orange R 21G) and yellow (IG-21R). This Multi Color Led Circuit is very easy to build at home.

LED lighting circuits are a simple and efficient way to provide illumination for a variety of applications. They rely on the relatively low voltage drop and high efficiency of LEDs, meaning that they can be connected in series or parallel to provide more intensity or longer runs. LED lighting circuits often contain additional components such as capacitors, resistors, and diodes in order to regulate the power of the circuit and reduce losses through heat loss.
