We know that LED is a two terminal semiconductor device. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly.

This is the first basic LED circuit I built many years ago in my school days and had given me immense pleasure to see glowing LED. For building this circuit you only need four things: LED- 1; Resistor ...

The above circuit is designed to drive a LED with 0.2A. This current rating is fixed by the Resistor R1 in the circuit. The formulae to determine the current is. I = Vref/R1 where, Vref is 1.25V for ...
