Light

Bring the ability to detect light levels to any project with the SparkFun TEMT6000 Ambient Light Sensor Breakout.

Use the Tessel 2 and the Johnny Five Inventors kit to explore the world of JavaScript enabled hardware through 14 awesome experiments!

Use GPS to have two objects, a base and a target, point towards one another. This can be used to aim a directional antenna (or in the case of this project, a laser) from one object to the other object at a distance that is only limited by your ability to provide the base station with the target's GPS location.
