Ever come home in the rain to find the door locked and your keys elsewhere? No? Lucky you then! For those who have had such an experience or never wish to, this project will let you open your garage door with nay but a smartphone/tablet/laptop/WiFi-thing and your super secret password! After all, who leaves their smartphone at home nowadays. The very idea!
All it takes is a network capable Arduino, a relay, a long network cable and a few other bits 'n bobs like wire and a soldering iron.
So how does it work? I'm so glad you asked! The Arduino hosts a little web page on your local network which you can access from any other device on the network, such as your smartphone, just like a normal website. When you input your password, the Arduino triggers a relay that acts like a wired garage door remote that you often see next to the internal door. This sets the garage door opening mechanism into motion, letting you through with the a new felt sense of control over your home!
So, shall we get started then?...
