on video Simple LED Chaser Light Circuit Using BC547 Transistors

 Today I am going to make an LED chaser circuit.Its effect is amazing.This circuit I will make using BC547 Transistor.

Connect all components according to this circuit diagram.

Solder +ve leg of all LEDs to the ring as you can see in the picture and circuit diagram.

Next we have to solder 220 ohm resistor to the -ve legs of LEDs as solder in the picture.

Next we have to connect transistors.

Solder collector pin of transistor to 220 ohm resistor as you can see in the picture.

Next we have to solder 10K resistors to the circuit.

Solder 10K Resistor between Base pin of transistors to +ve legs of all LEDs as you can see in the circuit diagram.

Solder capacitors to the circuit as given in the circuit diagram.

+ve pin of capacitor to Base pin of one transistor and -ve pin of capacitor to collector pin of other transistor as you can see in the picture.

Now we have to connect battery clipper wire to the circuit.

Solder +ve wire of battery clipper to +ve of all LEDs and solder -ve wire of battery clipper to emmiter pin of transistors as given in the circuit diagram.
