Running Effect LED pattern (2 circuit)

LED chaser circuit

1. LED Running Effect Without IC

Here is presenting a circuit diagram of LED chaser . The Main Advantage of this LED chaser is it does not require any ic or microcontroller.

This Circuit is made using mainly NPN transistors and capacitors and some resistors.

This LED chaser circuit produces a blinking effect that looks the same as Running effect in a particular direction. All LEDs blink as moving in one direction. We can also say that this is an LED running effect chaser circuit.

This is an easy circuit and it can easily construct at home by even who beginner in this field. 

There are 19 LEDs are connected in this circuit in A straight line. But You can connect in different shapes like circle, Heart shape, Arrow shape Etc. 

If you want to connect Ac light at the place of LEDs then need to modify the circuit using TRIAC and Optocoupler.

LED – 19 pc

Transistors 2N2222A –  3 pc


10K – 3 pc,    330 Ω – 3 

Capacitors 220 uf or 330 uf (for slow speed) – 3 pc ( 100uf for high speed )

12v battery or any dc source

2 . LED Running effect using IC 74HC595 and 555 

This running effect circuit made using shift resistor ic 74HC595 and 555 timer. Use the 9v dc supply for this circuit. The speed of running can be controlled using the preset RV1. By adjusting the 10k preset the pulse of oscillation of 555 timer ic can be adjusted and according to pulse rate at pin no 3 the blinking or running effect of LEDs controlled.
