 Awesome LED Running Chaser Circuit Using NE 555

Today I am going to make an LED Chaser circuit without using IC.This circuit is amazing and I will make this circuit using BC547 Transistor.This is Best LED Chaser circuit.

Firstly we have to connect emitter pins of all three transistors as solder in the picture.

Next we have to connect the capacitors to the transistors.

[Capacitor 1] - Solder -ve pin of 1st capacitor to Base Pin of 1st transistor and +ve pin to collector pin of 2nd transistor,

[Capacitor 2] - Solder -ve pin of 2nd capacitor to Base Pin of 2nd Transistor and +ve pin to collector pin of 3rd transistor and

[Capacitor 3] - Solder -ve pin of 3rd capacitor to Base Pin of 3rd Transistor as you can see in the picture.

Solder +ve pin of 3rd Capacitor to Collector pin of 1st Transistor using a wire as solder in the picture.

Next we have to connect 560 ohm resistor to the circuit.

Solder 560 Ohm resistors to all collector pins of the transistors as solder in the picture.

Next connect 10K resistors to the circuit.

Solder 10K resistors to Base pins of all three transistors as soldered in the picture.

Next connect all out wires of 10K resistors and 560 Ohm resistors to each other as you can see in the picture.

Now we have to connect -ve legs of all LEDs to each other as connected in the picture.

Next Connect a wire to +ve leg of LED-1 to +ve leg of LED-4,

Solder 2nd wire to +ve leg of LED-2 to +ve leg of LED-5,

Next solder 3rd wire to +ve leg of LED-3 to +ve leg of LED-6 as you can see in the picture.

Solder a wire to -ve leg of LEDs.

As you can see in the picture Yellow wire is solder to -ve leg of LEDs.

Solder -ve wire of LEDs to Common Emmiter pin of the transistors.

Solder wire of LED-1 to Collector pin of Transistor-1,

Solder wire of LED-2 to collector pin of Transistor-2 and

Solder wire of LED-3 to Collector pin of Transistor-3 as solder in the picture.

Now solder +ve wire of battery clipper to Out wires of 10K and 560 Ohm resistors and

Solder -ve wire of battery clipper to Common emitter pin of the transistors as you can see in the picture.

Now our circuit is completed so connect battery to the battery clipper and see LED is chasing.

This LED Chaser circuit gives best output.

NOTE: We can give Input Power supply 9V - 12V DC.
