Story

This project is for the World's Largest Ardunio Maker Challenge 2016. It uses an Ardunio MKR1000 and associated Windows 10 UWP app to control and send an email to a defined email address. This does require that the email address has an associated phone to provide notification but this is likely not an issue. Originally the idea was to send a notification through google cloud messaging to Azure and then to the phone. This did work but I was not able to work out a way to send the notification using UWP as the NotificationHubClient solution only works on C# console applications.

This is designed to be a temporary sensor rig that you set by pressing the button and on a noticeable change the program sends an email. Connection is done via WiFi using the Firmata protocol.

Currently the only sensors that are included are the PIR, Knock sensor and LDR. It is easily expandable with simple addition to code.

The system works by first turning on the power supply (connects automatically to wifi on power-up). A companion application (a Windows 10 Universal App) needs to be launched on a Windows 10 device (I've used a desktop computer) which acts as the controlling device. Then you would select the sensor you would like to use by switching the companion switch on the device to HIGH. This reads the current value of the sensor and sets it to the base value. This allows it to be used either to read HIGH or LOW (in the case of digital). Then when the value read by the sensor changes the system notices and sends an email to the address specified (can be extended to send a notification to a phone). To reset the sensor it is necesary to set the switch to LOW again.

I've adapted code from a variety of places including:

https://github.com/ms-iot/remote-wiring

https://www.hackster.io/windowsiot/basic-windows-remote-arduino-47eeb9

A lack of time has limited me on this project but I am happy I had a chance to mess around with Windows Azure Mobile Services and sending notifications even though I didn't end up being able to use it. Also Windows Remote Arduino was a good way to control Ardunio's but does complicate things a bit. However for the extra complication you can do a lot more with them. Potentially a RPi 2 would be a better fit for this project as it wouldn't require a separate control computer.

  README

  StandardFirmataWiFi is a WiFi server application. You will need a Firmata client library with
  a network transport in order to establish a connection with StandardFirmataWiFi.

  To use StandardFirmataWiFi you will need to have one of the following
  boards or shields:

  - Arduino WiFi Shield (or clone)
  - Arduino WiFi Shield 101
  - Arduino MKR1000 board (built-in WiFi 101)
  - Adafruit HUZZAH CC3000 WiFi Shield (support coming soon)

  Follow the instructions in the wifiConfig.h file (wifiConfig.h tab in Arduino IDE) to
  configure your particular hardware.

  Dependencies:
  - WiFi Shield 101 requires version 0.7.0 or higher of the WiFi101 library (available in Arduino
    1.6.8 or higher, or update the library via the Arduino Library Manager or clone from source:
    https://github.com/arduino-libraries/WiFi101)

  In order to use the WiFi Shield 101 with Firmata you will need a board with at least
  35k of Flash memory. This means you cannot use the WiFi Shield 101 with an Arduino Uno
  or any other ATmega328p-based microcontroller or with an Arduino Leonardo or other
  ATmega32u4-based microcontroller. Some boards that will work are:

  - Arduino Zero
  - Arduino Due
  - Arduino 101
  - Arduino Mega

  NOTE: If you are using an Arduino WiFi (legacy) shield you cannot use the following pins on
  the following boards. Firmata will ignore any requests to use these pins:

  - Arduino Uno or other ATMega328 boards: (D4, D7, D10, D11, D12, D13)
  - Arduino Mega: (D4, D7, D10, D50, D51, D52, D53)
  - Arduino Due, Zero or Leonardo: (D4, D7, D10)

  If you are using an Arduino WiFi 101 shield you cannot use the following pins on the following
  boards:

  - Arduino Due or Zero: (D5, D7, D10)
  - Arduino Mega: (D5, D7, D10, D50, D52, D53)

 *
 * You must configure your particular hardware. Follow the steps below.
 *
 * Currently StandardFirmataWiFi is configured as a server. An option to
 * configure as a client may be added in the future.
 *============================================================================*/

// STEP 1 [REQUIRED]
// Uncomment / comment the appropriate set of includes for your hardware (OPTION A, B or C)
// Option A is enabled by default.

/*
 * OPTION A: Configure for Arduino WiFi shield
 *
 * This will configure StandardFirmataWiFi to use the original WiFi library (deprecated) provided
 * with the Arduino IDE. It is supported by the Arduino WiFi shield (a discontinued product) and
 * is compatible with 802.11 B/G networks.
 *
 * To configure StandardFirmataWiFi to use the Arduino WiFi shield
 * leave the #define below uncommented.
 */

/*
 * OPTION B: Configure for WiFi 101
 *
 * This will configure StandardFirmataWiFi to use the WiFi101 library, which works with the Arduino WiFi101
 * shield and devices that have the WiFi101 chip built in (such as the MKR1000). It is compatible
 * with 802.11 B/G/N networks.
 *
 * To enable, uncomment the #define WIFI_101 below and verify the #define values under
 * options A and C are commented out.
 *
 * IMPORTANT: You must have the WiFI 101 library installed. To easily install this library, opent the library manager via:
 * Arduino IDE Menus: Sketch > Include Library > Manage Libraries > filter search for "WiFi101" > Select the result and click 'install'
 */

 *
