Sayanee Basu shows how to use Javascript to control devices using a Spark Core.

The Internet of Things is gaining momentum in the recent years as more embedded computing devices are being connected to the Internet. What does this mean for us web developers? This article will explore two common wireless protocols, Wi-Fi and BLE and will take you through the starting steps in connecting sensors and servo motors to the Internet. Then we will learn how to control these devices and access the sensor data using JavaScript!

The Spark Core is small, low power, and does all the heavy WiFi lifting, but will still let you do all kinds of tinkering to get your IoT project up and running. There’s a backend website platform ‘cloud’ that will let you send and receive data so, rather than having to access everything from your local network or trying to figure out how to tunnel into it, the Spark Core connects out to the Spark.io network for seamless connectivity. You can always set up your own protocols if you want, but you don’t have to. And that’s kind of the point!  The Spark Core ships hooked up the cloud, so you can worry about your things and how they integrate, instead of worrying about getting the cloud to work.
