• battery
• motion
• magnetometer
• light
• sound
• environment (temp, press and humidity)

note environment includes SHT31-D and BMP280 - compare the temp readings of both.

add record and stop buttons to start/stop logging data

looks like spectral data are integers but the characteristic is float. Check the documentation and adjust appropriately

Set up directory structure and helper files so that the project is compatible with the readthedocs requirements.

see Circuitpython Design Guide

log battery voltage over time and use this to calibtrate battery in terms of percent charge remaining. Use percentage of time remaining rather than percentage of useful voltage.

Perhaps express in term of time remaining.

use a bit mask to enable characheristics
include enable and disable functions in the core class
get the characteristic index from the uuid or include it in the
class structure {service}{characteristic}

eg gyro: {01}{02}
