In this tutorial, you will connect an Arduino UNO board to the WSO2 IoT Server and visualize the data gathered. The following subsections explain how you can work with the Arduino device type:

Before you begin

  • Make sure to have the following ready:
    • An Arduino UNO Board.
    • An Adafruit Wi-Fi Shield for Arduino.
    • An LED bulb connected to Pin 13. If you do not have an LED bulb, use the one on the Arduino board. The one on the board is connected to pin 13 by default.
    • A Resistor (example: 330 ohms)
  • Download the Arduino software.
  • Navigate to the <IOTS_HOME>/plugins directory and run the device-plugins-deployer.xml file.

    cd <IOTS_HOME>/samples
    mvn clean install -f device-plugins-deployer.xml
  • Start the WSO2 IoT Server broker, core and, analytics profiles in the given order. For more information, see how to start the WSO2 IoT Server.

    cd <IOTS_HOME>/bin
    ------Linux/Mac OS/Solaris ----------

Let's get started!

Starting the Arduino

  1. Sign in to the Device Management console.

     Click here for more information.
    Follow the instructions below to sign in to the WSO2 IoT Server device management console:
    1. If you have not started the server previously, start the server.

    2. Access the device management console.

      • For access via HTTP: 

        For example: http://localhost:9763/devicemgt/
      • For access via secured HTTP: 
        For example: https://localhost:9443/devicemgt/ 
    3. Enter the username and password, and click LOGIN.

      • The system administrator is able to log in using admin for both the username and password. However, other users will have to first register with WSO2 IoT Server before being able to log into the IoTS device management console. For more information on creating a new account, see Registering with WSO2 IoT Server.

      • If you are signing in as a different tenant user, the username needs to be in the following format <USERNAME>@<TENANT_DOMAIN>.

      By logging in you agree with the WSO2 IoT Server 3.3.0 cookie policy and privacy policy.

    4. Further, you need to provide consent for the details you want WSO2 IoT Server to use.

      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 Wi-Fi 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. 

Control the bulb

Once you start your Arduino, follow the steps given below to turn on or turn off the bulb connected to the Arduino board.

  1. Click Control Bulb under Operations on the Device Details page.
  2. Enter On to switch the control bulb on and click Send to Device. Enter Off to switch the bulb off.
