Modern Robotics Analog Example
Created 7/25/2017 by Colton Mehlhoff of Modern Robotics using FTC SDK 3.10
Reuse permitted with credit where credit is due

The Modern Robotics Core Device Interface reads analog input
using a 10 bit value meaning the Android Phone reads a value from 0 to 1023.
The FTC SDK supplies a "voltage". The SDK is scaling this value of 0-1023 to 1-5 with decimal places.

Configuration:
Analog Input on Core Device Interface "light"
Core Device Interface named "Device Interface Module 1"
