Grove – LED Bar v2.0
The Grove LED Bar is a 10-segment LED gauge bar and an MY9221 LED controlling chip. It can be used as an 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. Demo code is available to get you up and running quickly. It lights up the LEDs sequentially from red to green, so the entire bar graph is lit up in the end.
Please note that the example code libraries assume the use of a Grove shield.Â
