Description
The Modern Robotics Touch Sensor is housed in a sturdy housing with mounting holes on each side so it can be incorporated into a robot regardless of the building system. It is ideal to use as a limit switch or bumper switch. When depressed, internal LEDs will illuminate to confirm correct operation and the digital output to the host controller will switch from logic 0 to logic 1. |

FTC SDK
Android Studio Example Program
Download the below program for an example of how to read this Analog sensor. The FTC SDK will supply a value from 0-5 representing a voltage.
In your configuration file, name an Analog Input “light” and name a Core Device Interface Module “Device Interface Module 1”

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"
