Introduction: Simple Light Tracker
I recently got my first Arduino, the Arduino Mega 2560, about 1 week ago. After completing the basic tutorial exercises I decided to do my first mini project. I had seen several quite professional projects which featured light tracking and thought it would be a great learning exercise to imitate.
The project itself is very simple. It consists of just two light dependent resistors fastened to either side of a piece of cardboard, which itself is mounted at an angle on a 180 degree servo. This LDR's are each in series with a 2.2K resistor.
