Easy 3 Channel LED Flasher/Chaser

3 LED flasher circuit using transistor

Here is another type of LED flasher circuit but this circuit is also about same as my previous led chaser , here is some changing in this circuit.This is Very  Easy and beautiful LED chaser that is made using without any ic . only transistors, capacitors and resistors are used to make this LED chaser Circuit. This is 3 channel Flashing chaser circuit, 3 step Flashing effect blink  One by one. You can connect Relay and then high voltage AC bulb for blinking purpose. The main working function of this circuit is based on to capacitor charging and discharging timing through the transistor switching.

You can use 3v to 12v DC power supply for operating this led flasher circuit. Use battery or any ac to dc adaptor.

12v led flasher circuit

All transistors are BC547 are used in this circuit. Capacitors you can use between any value of 100uf-470uf. Circuit is very simple.This is one of the best, easy and effective circuit for Beginners and LED lovers. You can arrange LEDs in different patterns as you like and can connect more LEDs with one transistor upto 6. If you want to connect more LED then you should connect extra NPN transistors with the all transistors . Use can also use transistor 2N2222 at the place of BC547 and connect Upto 20 LED with one transistor.
