  Accelerometer service

  This example creates a BLE peripheral with service that contains three
  characteristics, each an analog input value to the microcontroller. It
  was designed with the ADXL337 accelerometer in mind, but any three analog
  inputs will work as well.

  The circuit:
  - Arduino MKR WiFi 1010 (firmware version 1.2.0 or later)
