The SunSwitch sensor is basically an array of LEDs arranged on a curved surface. The sensor array is divided into an east and west array and separated by a vane which cast a shadow. When LEDs are exposed to direct sunlight within their focus angle they produce a small current (micro-amps) and associated voltage which is compatible with TTL inputs. Solar Tracker

In this lab we created a solar seeker, namely a simple device that tracks a light source. Such a device can be used in satellites to keep the solar panels aligned with the sun, or in search and rescue robots that try to guide trapped people towards light. In order to implement the solar seeker we used two Cadmium Sulfide (CdS) photocells and a servo motor that rotated the photocells. e72 . lab 7 : Solar Seeker
Arduino Platform - Differential Gap Control (Solar Tracker) Introduction This article gives a very simple introduction into writing a differential gap controller on the Arduino platform. I have used a Duemilanove for this example.
Introduction My solar tracking mirror array or “death ray” as it is affectionately referred to by my friends is actually a heliostat. A heliostat is technically any device that tracks the movement of the sun, but most often the term refers to a device that orients a mirror to reflect sunlight continuously onto a specific target.

I Got some solar cells since two months ago, but it wasn't until the last week I decided to put those solar cells to work. I really didn't have any good idea for it, I was thinking to use it to power toys or some homemade projects. Finally, I thought I can use those solar cells to charge rechargeable batteries.
