LED light chaser using 74HC595 Shift Register & Potentiometer

This Arduino project is similar to the other light chaser project I done, but I’ll be using a shift register & will be controlling 8 LEDs instead.


In this project, a shift register is used to control the 8 LEDs attached to the breadboard, turning on all the LEDs one after another and turning off all of it after all the LEDs are turned on. The potentiometer is used to set the time delay between each LEDs, where I constrained the range from 0 – 1023 to 10 – 500.
