Validation Test for Dev Kit Blinks

1. Validate RGB on all 6 faces together
2. Validate RGB on each of the 6 faces individually
3. Validate communication w/ awake neighbors
4. Validate cold sleep (<0.2µA)

Cycle RED, GREEN, BLUE to verify all 6 LEDs light

• look for equal brightness
• look for discreet light, i.e. no two colors should be on at the same time

Press button to switch modes

• When button is pressed down, the lights should glow WHITE (RGB together)

Individual mode

• a single R, G, or B LED lights up and cycles through all 6 faces
• continues to the next color in line and repeats
• makes it obvious if a single LED is faulty

Communication mode

• Low level white by default
• when neighboring Blink is awake, it will glow bright white

Sleep mode

• instantly starts "cold sleep" requires button press to be woken
• cold sleep is reserved for ~10 minutes after warm sleep by default

A little bit of serial printing just in case we want to also look at what is executing via serial monitor
