Fun Flashing Led Circuit Using Transistor

In this video i ve shown how to make a simple led flasher circuit using transistor.

Flashing led circuit using transistor. To understand this circuit you need to know how voltages and currents behave around resistors capacitors and diodes which is something you can learn in ohmify. The speed of blinking can be changed by changing the value of capacitor c1 and c2. A driver circuit is also very useful if you are experimenting with pulse width modulation pwm techniques where the goal is to control the brightness to create a dimming and.

Both npn transistor you can use of bc547 548 or 2n2222. How to make simple led flasher using transistorfollow us on website. Of course you will need a breadboard wire jumpers and a power source.

The flashing rate could be varied either by changing the value of r1 or c1 or both together. R1 2k7 r2 100 ohms t1 bc 547 c1 100 uf to 470 uf. Parts list for the proposed single transistor led flasher circuit.

Usually the signal from a microcontroller or logic gate does not possess sufficient drive current to power an led directly. Use 9v or 12v battery or adaptor for this circuit. The parts list includes.

This simple led flasher blinker circuit made by using two npn bc547 transistor and some resistors and capacitors. If the led has a higher power requirement then it is best to use an npn transistor as a driver. An led driver is an electronic circuit that utilises a transistor to switch power to an led.

This circuit can be operated using dc 6 12v supply. Simple blinking led circuit. The circuit is built using transistors resistors capacitors and leds.
