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 ...

I have used Red and Green LED’s. When node A is positive green LED glows while when node B is positive, Red LED glows. This indicates polarity of the input d.c voltage . 2) LED as a Continuity tester: ...

The flasher circuits below operate on a single 1.5 volt battery. LED flasher circuit diagrams. The circuit on the upper uses the popular LM3909 LED flasher IC and requires only a timing capacitor and ...

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.
