Electronic and Arduino enthusiasts searching for an Arduino project to keep them busy this weekend may be interested in a new Arduino Mega fingerprint door lock.

DIY Arduino smart lock with voice recognition access 1:19 pm July 18, 2022 By Julian Horsey Arduino enthusiasts, makers and those of you looking to learn more about electronics.

He has fashioned an Arduino-powered door bolt that locks itself whenever you open an incognito browser window. Always nice when a computer gives you a helping hand.

The hack is still pretty hardware intensive, but Arduino fans will love this clever hack—especially if you're the type that locks yourself out of your room a lot.

Perhaps you could create an Arduino device to lean on the door right before the Arduino device bolts the door. It's not clear if the lock unlocks the door when you close that incognito browser.

If you're sick of using your boring old keys to unlock your door, Make has a guide for using and Arduino to power a lock that you can control with your smartphone.

He used 1 Arduino Mega 128; 1 DC barrel jack, 5-mm outer diameter, 2.1-mm inner diameter; 1 5.6k resistor; and 1 Onity door lock. The device hacks in through the lock’s data port. Brocious initially ...

With that out of the way, they installed a latch and servo motor inside the cavity, the latter of which is controlled using an Atmega328p with the Arduino bootloader.

The security flaws on this common hotel keycard lock are nothing short of face-palmingly stupid. Look closely at the picture above. This is a hotel room door swinging open. The device he holds in h… ...
