 DIY LED Flasher Circuit Using NPN Transistor | Simple BC547 Project with Diagram

Learn how to create a DIY LED Flasher Circuit Using NPN Transistor. DIY three-string star-shaped LED flasher using NPN transistors and basic components. This simple 9-volt circuit tutorial is perfect for beginners and electronics enthusiasts. Follow along with the step-by-step instructions and circuit diagram.

An LED flasher circuit is a circuit which flashes the LED- meaning turns it ON-OFF, ON-OFF, ON-OFF.


The BC547 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter. Typically NPN transistors are used to “switch ground” on a device, meaning, they are placed after the load in a circuit

Hi! here is how you can make the simplest LED flasher circuit using single transistor. This circuit is known as esaki oscillator.

When capacitor charges and reaches certain voltage breakdown occurs in Emitter collector juction of transistor and current starts flowing from capacitor to transistor and LED.

components:

* 2N2222 transistor

* 330 ohm resistor

* 4.7 ohm resistor

* 220uF capacitor

* LED
