Furthermore, it is comprised of a 10 segment LED gauge bar and an MY9221 LED controlling chip. The 10 LED bars in the LED bar graph include one red, one yellow, one light green, and seven green bars.

Demo code is provided in the ATTACHMENT section to light up the LEDs sequentially from red to green, so the entire bar graph is lit up in the end. You can create your own programs and run on this LED Bar
