This project is built for fun-loving users to create a 24 LED bar-graph for light effects that can be driven using Arduino or another microcontroller. The project consists of 74HC595 x 3 chips, and 24 LEDs of Red, Green, Blue, and Yellow colors.

The project helps the user to experiment with serial-in and parallel-output shift registers. Each 75HC595 chip provides 8 outputs which is connected to the individual LED along with current limiting series resistors. This board can be used in applications such as Light effects generator, Bargraph voltmeter, Current meter, Audio VU meter and display sensor value on bar-graph.
