Connect your Arduino to Temboo with a WiFi Shield

In this tutorial, we'll show you how to use the Adafruit WiFi shield to send an email from an Arduino using Temboo. The fundamentals shown here apply to any board and wifi shield combination.

This sketch uses our Google > Geocoding > GeocodeByAddress Choreo. You'll also need the Adafruit WiFi Shield and a compatible Arduino board.

Get Set up

1Make sure you have a Temboo account. If you don't already have one, you can register for free.

2Next, make sure that you've got the latest version the Arduino IDE installed.

3You'll also need to download the Adafruit CC3000 WiFi Shield library from Adafruit's Github.

Auto-Generate the Sketch

4Go to the Google > Geocoding > GeocodeByAddress in our Library.

5Turn IoT Mode ON at the top of the Choreo page and select Arduino from the drop down menu to the left.

6Select the Adafruit WiFi shield from the "How is it connected?" drop down menu.

7You'll now see a popup window that prompts you to provide a name, and the type of shield you're using. You'll also need to know the Security settings of your wireless network, the Wireless Network name and wireless network Password. When you press Save, Temboo will add this shield to your profiles so that you can use it later.

Setting up the WiFi shield configuration on the Choreo Page


8Now that you've set up your shield, you're ready to try the Choreo in the browser. Fill in the required Address input.

9Save the inputs into a profile for the next time you'd like to run this Choreo by clicking Save Profile at the top of the INPUT box. Give your profile a name, and press Save again. Then click the Run.

10In the OUTPUT box, you should see the Geocoding information returned by Google in XML format.

11If you'd like the Choreo to be triggered by a sensor event, or if you'd like the Choreo result to trigger an actuator event, you can specify conditions above and below the Choreo inputs and we'll generate the application logic code you need.

12Scroll down past the OUTPUT section to the Code snippets. Copy and paste the code snippet into your Arduino IDE.

13You'll also need to create the header file for your sketch, where your Temboo account credentials and shield information are stored. To incorporate it into your sketch, you'll create a New Tab in the Arduino IDE and call it TembooAccount.h.

14Copy the code snippet in the HEADER FILE found directly following the code snippet that you just copied and paste it into the TembooAccount.h tab.

Running the Sketch

15That's it, now your code is ready to upload! Once you upload the sketch to your board, open the serial monitor and you should see the success message indicating that your email has been sent. If you sent the email to yourself as a test, you should see a new email from your Arduino in your inbox.

What Next?

Now that you know how to connect your Arduino to Temboo using the Arduino Ethernet shield, you're ready to create a project that uses auto-generated code from any of our 2000+ Choreos. We'd love to hear about what you make - hey@temboo.com.

Once you've got your code up and running, you're ready to move on and do more. From monitoring your running applications, to moving your generated Temboo code to your preferred development environment and sharing it with colleagues, collaborators and friends - we've got you covered.
