• Microsoft Azure account (free trial or DreamSpark subscription will do)

Hardware components:

• Raspberry Pi 2 (Model B)
• Micro-USB power cable
• LAN cable or RasPi Wifi dongle
• Breadboard and wires
• Temperature sensor (TMP36)
• ADC converter (MCP3208)
• Monitor screen and HDMI cable (for RasPi)

1. Set up your local working space
2. Set up Raspberry Pi component (TemperatureMeasurement)
3. Set up SignalR web API on Microsoft Azure (SimpleIoTSignalR)
4. Set up User Device Client (TemperatureClient)

• Download project folder to your local PC
• Either "Clone in Desktop" (if you have the GitHub desktop app), or "Download ZIP" (and extract the content manually)

• Create a basic web app on your Azure portal. Log-in here

• If successful, you should see the web page below when you navigate to the URL you specified

• Open the project solution /SimpleIoTSignalR/SimpleIoTSignalR.sln in Visual Studio

• Right-click on the project name SimpleIoTSignalR and select Publish..

• Select Profile on the left panel and then Microsoft Azure Web Apps

• You should be prompted to log-in to your Azure account

• After successful log-in, select the web app you created earlier

• Select Publish without changing any settings on the dialog

• If successful, you should see the new web page below when you navigate to the URL you specified

• Connect the hardware components as per pictured below

• Download and set-up Windows 10 IoT Core on your Raspberry Pi 2, instructions here

• Connect your RasPi to the Internet, either via LAN cable (wired) or Wifi dongle (wireless)

  • Ensure that your RasPi and development PC are on the same network
  • To check the IP address of your RasPi, you need to connect it to a monitor screen

• Open the project solution /TemperatureMeasurement/TemperatureMeasurement.sln in Visual Studio

• Open the file SignalRClient.cs for edit

• Change the SignalR web API URL to the one you created earlier in Step 2, as per pictured below

• Build the solution via the Remote Machine option, as per pictured below

• Enter the IP address of your Raspberry Pi, select None for Authentication Mode

• To check if the app is working correctly on your RasPi, connect it to the monitor and it should appear like this below

• Open the project solution /TemperatureClient/TemperatureClient.sln in Visual Studio

• Open the file SignalRClient.cs for edit

• Change the SignalR web API URL to the one you created earlier in Step 2, as per pictured below

• Build the solution via the Local Machine option, as per pictured below

• A desktop app should run like this below

• This Windows Universal App client can run on any Windows 10 devices (e.g. Windows PC, mobile, Xbox)
