Imagine the OLED CO2 Monitor SCD30 example code, but with more polish.
- Reliable startup (Delaying helps; I don't know why yet. Voltage stabilization?)
- Prose description of CO2 level
- Fahrenheit conversion
- NeoPixel CO2 level color codes
The NeoPixel brightens if the color just changed. Toggle the display and NeoPixel with button A and button B.
