Home automation has been a hot-button topic time and again since the dawn of the personal computer age. These days, thanks to modern communications technology, it’s possible to do some pretty cool stuff. [Brad Harbert] decided to automate his garage door, controlling it over the Internet.
The build relies on a Particle Photon to do the heavy lifting of connecting the door to the Internet. Particle offer a cloud service that makes setting up such a project easy for the first timer, and [Brad] was able to get things working quickly. A relay is used to activate the garage door remote button, as it was desired to leave the main control board of the garage door opener untouched. Reed switches are used to sense the position of the door, and [Brad] coded a state machine to ensure the door’s current state is always known.
It’s a simple project, but [Brad]’s use of state machine techniques and position sensing mean it’s less likely he’ll get home to find his garage open and his possessions missing. If you’re new to programming simple physical devices, you could take a page out of his logbook. Of course we’ve seen similar builds before, like this one from parts from the scrapbin.
