Detailed Description

I2C 10-segment LED gauge bar.

The LED segments are as follows:

one red
one yellow
eight green

This twig uses a MY-Semi MY9221 LED control chip. Each LED segment can be individually controlled, and set to different intensity levels.

Connect the OLED display to the right-hand-side GPIO interface.
