LED (LIGHT EMITTING DIODE)

LED and Configuration of LED

     The operation of LED is similar to diode which has two terminals, anode and cathode. In the standard form, the long terminal represent anode and the short terminal represent cathode. . One of the legs with flag must be connected to ground and the other must be connected to 5 volt. LED exit in many form of colors. A normal LED use 5V and 5mA to operate. And through LED the current status of the system can be known. A 1KΩ resistor is connected series with the LED to limit the current pass through LED is 5mA.
