Amazing BC547 and 555 IC led chaser

 Amazing BC547 and 555 IC led chaser

Today I am going to make an LED Chaser circuit using NE555 IC and BC547 Transistor.This LED Chaser is different from other LED Chasers circuit.

Connect emitter pin of one transistor to base pin of other transistor and like this we have to connect all transistors as you can see in the picture.

Solder 10K resistor to base pin of all transistors and other side of 10K resistor connect each other as connected in the picture.

Next solder 330 ohm resistors to +ve Legs of all LEDs as you can see in the picture.

Next solder -ve legs of all LEDs to Collector pins of all transistors as solder in the picture.

Next connect +ve Legs of all LEDs to each other as solder in picture.

Connect Anode of 1N4007 Diode to 10K Resistors and Cathode to +ve legs of all LEDs as you can see in the picture.

Solder 2.2K Resistor between Anode and Cathode of 1N4007 Diode as you can see in the picture.

Next Solder +ve pin of 25V 470uf capacitor to 10K Resistor/Anode of Diode and -ve pin to Emmiter pin of 5th transistor as you can see in the picture.

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.

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.
