For an interesting project with younger people or just for fun, you can build a device that tracks the sunlight outdoors or any other strong source of light. By using an Arduino that measures the levels from five light-dependent resistors, it can determine from which direction the light is the strongest. It then controls two continuous-rotation servos to move the device in the direction towards the light source. Although the creators used a ... lot of cardboard, you can recreate it from anything spare. For example:
To get started with your own sun tracker, check the instructions out here. And we're on twitter and Google+, so follow us for news and product updates as well.
If you're working with Arduino projects like the sun tracker that require some external circuitry, consider one of our range of Protoshields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
