Learn 4: Experiment With Color Sensing

The color sensor is new to us in this project so let’s take a brief look at how it works.

Our perception of color is due to the colors of light that different objects reflect and absorb. The color sensor works in exactly the same way. It shines a white light at an object or surface and records the amount of each color in the reflected light. It can also record the intensity of the reflection (the “clear” value).
