on video very smmoth led blinker use to bc547 transsitor


 Led flash for alerts – led blinking using transistor bc547

The Led flash for alerts – led blinking using transistor bc547, you heard about these word in anywhere. because the flashing or blinking led is using in automobiles, signal tower, and other electrical and electronic devices.


In most of the motorcycle, the backlight is made up of led. when we applying the brake the led starts to blinking to giving as alert information.


so in this article, I’m going to explain how to build a led flasher. The free PCB you will get from the bottom of this site. This circuit is working based on the two transistors. This two-transistor LED flasher circuit is easy to build. so follow every step and learn about how to make your own led blinking circuit.

led blinking using transistor bc547

The circuit contains two transistors.


BC 547 NPN transistor

BC 557 PNP transistors

These two transistors are the main components for this circuit. The base of the PNP transistor connected to the collector of the NPN transistor. And also Base of the Npn transistor connected to the collector pin of PNP transistor.


so this circuit will act as a low switching function. First, the PNP transistor Get activated and led goes to glow and the NPN transistor drives the voltage to on PNP transistor.


Then the cycle will be continued and the led start to flashing at each time of the switching occurred in the transistors.

The working voltage of this circuit is 9v dc supply. you can also apply 12v dc without any problem.


Components for Led flash for alerts

BC547 transistor – 1

BC557 transistor – 1

led

1m ohm resistor

1 uf 25v capacitor

9-12v battery

Application of led flasher circuit

you can use it on your bike as a brake signal

using for decoration

alert message

boundary separation

hobby electronic circuit

you can use ut on your charger circuit ( Check how to use it )

in amplifier power-on indicator

cut off circuit

alert message

alert notification.
