Chapter 8. Machine-to-Machine Communication

Most of the projects in this book rely on the Photon or Core either being completely independent (once programmed) or being controlled through a web browser or other user interface over the Internet. In this chapter, you will learn how to make one Photon/Core speak to another, or even many other Photons or Cores.

In the previous chapter, when you used IFTTT to monitor the temperature on a Photon/Core, IFTTT checked the temperature Variable on the Photon only every 15 minutes. The reason they limit it in this way is that otherwise there could be potentially huge volumes of web and email traffic if everyone’s triggers were being monitored continuously. This type of checking on ...
