The ThingSpeak API allows you to build "Internet of Things" applications. Use the API to create cloud applications that interact with sensors and controls from anything that supports the HTTP protocol. The ThingSpeak API is able to interface with devices from Arduino and ioBridge, iPhone and Android mobile devices, home automation systems, robots, thermostats, industrial controls, etc. ThingSpeak also supports integration with external web services such as Twitter, Prowl, Twilio, and WeatherBug, and Foursquare, by using the ThingHTTP app. In addition to the free hosted API, the ThingSpeak API is open source and available on GitHub for download on private servers.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
