 How To Make Simpal LED Flasher Using BC547 NPN Transistor Circuit Diagram

This is the making of a LED chaser which is based on a NPN transistor (bc547) and some bunch of other commonly hardwares such as resistors and capacitors

bc 547 (NPN transistor)

9pc blue led (5mm/3mm)

10 kilo ohms resistor (0.25w)

22 ohms resistor

100uf capacitor

19 SWGcopper wire

breadboard

enamelled copper wire

so i have made tthis flasher to work in 12volts but you could also make this project in 5v which is more convenient to work with

The total structure of this project was made by using copper wires which are then bend and soldered to shape. I have chosen a rectangular cuboid structure of this build as it is easy to build

here i have usde 19SWG copper wire

THE CIRCUIT MAKING

the whole base as the ground terminal

Connect emittor (3rd pin) of the three transistors to ground

Connect 10 kilo ohms resistors to the base (2 nd pin) of the three transistors

Connect the 100 uf capacitor's negative to the base of the three transistors

Connect 22 ohms resistors to collector pin (1st pin) of the three transistors

connect the positive terminal of the capacitors to the proceeding transistors collector pin (1st pin)

connect all the resistors unconnected end together asit is the positive terminal of this led flasher

Connect the positive part of every led set to the collector pin (1st pin) of the three transistors
