Running Light Chaser Circuit

Introduction: Running Light Chaser Circuit

Source :http://www.theorycircuit.com/running-light-chaser-circuit/

This running light chaser circuit consist of IC555 timer and IC4017 decade counter, This IC CD4017 drives upto 10 LEDs. Speed of glowing LED can be controlled by variable resistor in timer (IC 555) which is setting frequency output of timing pulse.

Step 1: Circuit Diagram

This circuit has three stages, the first one is pulse generator here we use timer (IC555) circuit to produce astable pulses. The second stage is decade counter (CD4017) this will count the astable pulse in a circle pattern. Final section is output LEDs, here we can connect different colour LEDs to make the output beautiful.
