Creating projects using LED having great fun especially LED Chaser. But for that, we need an IC that is CD4017 and 555 IC. But here in the circuit, we use only simple transistors to create this led Chaser.
You can use any number of LEDs in this project just by simply increase the number of transistors and capacitors.
What is a Led Chaser?
LED chaser is a simple set of LEDs that blink after a short time of interval one by one. We can easily create a led blinking circuit using a transistor, by simply using this formula we can also make a LED chaser circuit by using transistors.
In the circuit, we don't use any IC that is cd4017 and 555. Only use a couple of transistors to create the circuit.
1) 3x BC 547 Transistor
2) 3x Led
3) 3x 1k and 10k Resistance
4) 4x 220uf capacitor
5) 100uf capacitor
