DIY Arduino Powered Single Pixel Scanning Camera

By on December 18, 2018

Created by Tucker Shannon, the single pixel scanning camera uses a pair of stepper motors which directs the RGB color sensor (Adafruit TCS3472) in a square spiral for image acquisition: all powered by an Arduino Uno SBC.

If you are interested in building your very own Arduino powered single pixel scanning camera, all you need is:

  • Arduino Uno
  • Adafruit RGB Colour Sensor TCS34725
  • x2 BYJ-48 Stepper motor with drivers
  • 3mm OD aluminium tube
  • x20 M3x6mm fasteners

Alternatively a photoresistor can be used in place of the RGB sensor for black and white photos if preferred.

The device looks like something akin to some sort of auto-turret, and directs the sensor in a square spiral for image acquisition. The resulting pictures are certainly low-res, but good enough to pick out recognizable forms with a little imagination.

Code for the project can be found on GitHub and print files are on Thingiverse.
