An overview of Milo's lights and what they mean
Milo has 2 sets of lights (LEDs) on the front, communicating information about Milo's status and settings:
- A ring of 8 white LEDs around the Milo button. The LED ring provides supporting information at a quick glance.
- One 2-color LED at the bottom of the LED ring. This is mainly showing power and battery status.
White LED ring
Think of the 8 LEDs as an analog clock-face with LED_1 at the 1 o'clock position and LED_8 in the 11 o'clock position.
