The running LED light generally can not adjust the speed of light.This circuit can adjust the speed of light as needed.Make this circuit can used more versatile.Operation of the circuit is divided into two parts
1.Frequency genarator.
2.Display.
The circuit uses a 555 timer and a 5stage johnson counter (CD4017) having 10 decade output.That outputs (Pin 2,3,4,7,10etc)becomes high and low when the input pin (Pin14) receives pulses from generator IC(555).
Pin 9 is connected to the Pin 15 (Reset Pin) to stop counting.So that the cycle repeats.VR 1 adjust the speed of light.Try it at home and give me a comment ....
