| 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.
