Face recognition is an amazing field of computer vision with many possible applications to hardware and devices. Using embedded SOC platforms like the Raspberry Pi and open source computer vision libraries like OpenCV, you can now add face recognition to your own maker projects! In this project, I’ll show you how to build a door lock which unlocks itself using face recognition running on a Raspberry Pi.

For this project, you need basic skills related to Linux, Raspberry Pi and electronics. If you are not confident with Raspberry Pi you can take any free tutorial from YouTube.


  • Raspberry Pi
  • SD Card
  • Raspberry Pi Camera
  • Servo Motor
  • 10k -ohm   1/4 watt resistor
  • Push Button
  • Hookup Wires
  • Power Supply for Pi and Servo
  • Wood / Glue and Misc for Construction


My Door Lock is based on this below adafruit Tutorial by Toiy DiCola

Please follow his tutorial to learn how this is made. Below is a video of my project’s demonstration.
