Navigate by Visible Light
Light sensors are used in all kinds of robotics, industrial, and commercial applications. Next, let’s teach your ActivityBot to navigate by visible light. Using a pair of small light sensors, called phototransistors, your ActivityBot can measure and compare the light levels on its right and its left. It can then turn toward the brighter side as it navigates. This way, the ActivityBot can be programmed to follow a flashlight, or find its way out of a dark room to a bright doorway.
