Code Introduction
This IoT Code Guidebook is a supplement the IoT Project Guidebook.
What's in this Guidebook?
This guidebook contains a series of IoT code tutorials to help you get familiar with using your IoT electronics kit to build smart devices and program apps for them.
In addition, this guidebook contains coding references to help show and explain how to create a device app and web app that interact with each other through the internet. There are also references that show and explain how to connect specific inputs and outputs to your device and how to add code in your device app to control the inputs and outputs.
Finally, this guidebook also contains links to external resources, such as an online code editor (web IDE) for creating your device app, programming language references, and additional experiments for learning how to use your IoT kit.
Be sure to check out the recommended prerequisite knowledge that will help ensure students are successful with the IoT code tutorials and IoT project.
HOW TO COPY CODE: When using these coding tutorials and references, you can copy a code block by clicking the copy icon displayed in the upper-right corner of the code block.

}Your IoT Electronics Kit
This guidebook is tailored for an IoT electronics kit called the SparkFun Inventor's Kit for Photon, which will simply be referred to as the Photon kit.
SparkFun sells a variety of other sensors and outputs that can be used with the Photon kit. If possible, it is highly recommended to add an ultrasonic sensor to the kit for more design possibilities.
NOTE: Your instructor may have provided you with a different IoT electronics kit. If your IoT kit uses Arduino, then you can still use this guidebook to help get familiar with using your IoT kit to build smart devices and program apps for them. The Photon kit is programmed using a language called Wiring that is nearly identical to Arduino. In addition, the Photon circuit board is similar to an Arduino circuit board (though there are a few differences).
