After being faced with the challenge of levelling a camera atop a 30' mast (as shown below), Kevin Palivec turned to the Arduino platform for a simple and workable solution. By using a small board an an accelerometer, he created a device that can display whether the camera is level - or show which way it is leaning. An electronic replacment for the old bubble-meters. However it simply works and is another example of how you can make your own devices to solve real-world problems with Arduino.

This tiny 3-axis accelerometer module can operate in either +/-1.5 g or +/-6 g ranges, giving your project the ability to tell which way is up. Ideal for robotics projects, tilt sensors, vehicle data loggers, and whatever else you can dream up. For more information and to order, click here.
