Light Seeker

Light Seeker

So, me and Darth (Rodrigo Otávio) made this ‘Light Seeker’, which is basically a pair of full rotation servos (360º) and a couple of photoresistors to sense the light intensity and find out where it comes from.


  • 1x Arduino Duemilanove
  • 2x Parallax Continuous Rotation Servos
  • 2x Photocell resistor
  • 2x 1kΩ Resistor
  • 1x Protoshield (for mouting)
  • 1x Battery pack (4 AA)

Source Code

We consulted this tutorial for the photocells, but used a 1k resistor instead of a 10k, since I wanted the sensor more sensitive.

The source code can be downloaded here.
