Short Bytes: You can create an internet-connected smart door lock using your Raspberry Pi 3 single board computer. It can be unlocked over a WiFi connection using a smartphone and a custom app. The DIY procedure for the door lock has been explained by the Hacker House team in their YouTube video.What can be the best use of your recently brought Raspberry Pi board? You can make a stick computer, a Linux-powered phone, a drone killer, and much more. How about making a smart lock using a Rpi board which you, and your friends, can unlock using a smartphone. And you don’t need to be in the close vicinity of the lock.
A Youtube video demonstrating a Rpi-based deadbolt actuator has been uploaded by the channel Hacker House. As the video explains, the smartphone-powered lock works without existing lock setup. So, you don’t need to dismantle it inside-out.
The team says many smartphones can be used to control a single door lock with the help of a custom app – built using Blynk – that requires a username and password. The app also sends lock/unlock notifications on the devices. However, it needs a WiFi connection, so, make sure you have an extra door to access your home, in case, the WiFi goes out.
