In this chapter, you’ll learn to use the Color Sensor by adding it to the EXPLOR3R (see Figure 7-1) so the robot can detect colored paper, follow lines, and respond to light signals.
Figure 7-1. Using the Color Sensor, the EXPLOR3R can detect colors and follow lines.
The Color Sensor can detect the color of a surface (in Color mode), the amount of light reflected by a surface (in Reflected Light Intensity mode), or the brightness of ambient light (in Ambient Light Intensity mode), as shown in Figure 7-2.
You’ll create programs for the EXPLOR3R to try out each of these modes using the Wait, Loop, and Switch blocks, ...
