Description

Grove – LED Bar is based on an MY9221 LED controlling chip and with a flexible power supply and support 3-5.5DC. There are 10 LED bars in the LED bar graph: one red, one yellow, one light green, and seven green bars. A 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. Want to go further? Go ahead and code your own effect.
