Arduino

Connect an Arduino UNO board to the WSO2 IoT Server and visualize the sensor data. The following subsections explain how you can work with the Arduino device type:

Prerequisites

• An Arduino UNO Board.
• An Adafruit WiFi Shield for Arduino.
• An LED bulb connected to Pin 13. If you do not have the pin use a pin available on the board.
• A Resister (example: 330 ohms)

Starting the Arduino

1. Sign in to the Device Management console.

    Click here for more information.

   Follow the instructions below to sign into the IoTS device management console:

   1. Start the server.

   2. Access the device management console.

      • For access via HTTP: 
http://<HTTP_HOST>:9763/devicemgt/ 

        For example: http://localhost:9763/devicemgt/
      • For access via secured HTTP: 
        https://<HTTPS_HOST>:9443/devicemgt/ 
For example: https://localhost:9443/devicemgt/ 

   3. Enter the username and password, and sign in.

      The system administrator will be able to log in using admin for both the username and password. However, other users will have to first register with IoTS before being able to log into the IoTS device management console. For more information on creating a new account, see Registering with IoTS.

      

   4. Click LOGIN. The respective device management console will change, based on the permissions assigned to the user.
      For example, the device management console for an administrator is as follows:
      

2. Click Enroll New Device.
   
3. Click Arduino to enroll a device of the type Arduino.
   
4. Mount the WiFi shield onto the Arduino-UNO board.
5. Connect the LED bulb to the Arduino as shown below.
   
6. Download the Arduino agent:
   1. Click Download Sketch.
   2. Enter a preferred name on the download agent form.
   3. Click DOWNLOAD NOW.
7. Create a folder by the name ArduinoBoardSketch and move the downloaded agent and the source files to it.
8. Configure the following fields in the ArduinoBoardSketch.h file, which is in the Arduino agent file you downloaded.

   • WLAN_SSID - Provide the SSID of your Wi-Fi network.

     The WLAN_SSID cannot be longer than 32 characters.

   • WLAN_PASS - Provide the password of your Wi-Fi network.
   • SERVICE_PORT - Provide the http port of the WSO2 IoT Server.
     Example: 9763
   • server - Provide the IP address of the WSO2 IoT Server.
   • deviceIP - Provide the static IP address of Arduino.

9. Burn the sketch onto your Arduino board and run the program.

   1. Download the Arduino software.
   2. Open the Arduino agent file using the Arduino software.
   3. Add the Adafruit_CC3000_Library-master library. For more information, see Adafruit_CC3000_Library.
   4. Click the upload button to run the program.

When the Arduino starts it will publish the internal temperature to the WSO2 IoT Server. 

Try it out

Once you start your Arduino you can try out the following actions:
