Grove LED Bar is comprised of a 10 segment LED gauge bar and an MY9221 LED driver.

It can be used as a indicator for remaining battery life, voltage, water level, music volume or other values that require a gradient display.

There are 10 discrete LED bars in the LED bar graph: one red, one yellow, one light green, and the rest green.
