LED Bar v2.0 (Grove 104020006) component

LED Bar is comprised of a 10 segment LED gauge bar and an MY9221 LED controlling chip. 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 LED bars in the LED bar graph: one red, one yellow, one light green, and the rest green. It lights up the LEDs sequentially from red to green, so the entire bar graph is lit up in the end.
