Grove Zero - Color Line Follower
The Color Line Follower is an input module which detects line and colors on the surface beneath it.
Module Category: Input
What Is It
The Color Line Follower is an input module which detects line on the ground and reognises the colors it sees on the surface beneath it. By connecting it to the chassis module, it can be turned in a compact line following car.
Grove Zero Series Introduction:
Grove Zero is a set of programmable elctronic building blocks which snap together with magentic connections & are used in conjuction with graphical programming software to achieve creative and functional projects. Grove Zero can be used boths as a tool to foster children's creativty as a classroom tool for STEM education. Learn more about the series here.
If this is your first experience with the Grove Zero series, we recommend that you purchase introductory kits such as the Starter Kit, Car Kit or Bit Kit, which include instructional documentation to help you get familiar with this educational series.

How It Works
The Color Line Follower contains one color sensor (the middle one) and four light sensors. Each light sensor is paired with a white LED which is located next to the light sensor.
The light emitted from the LED is reflected by the ground surface and then received by the paired sensor. By measuring the received light, the color sensor can detect the color of the surface while the light sensors can only tell if the surface is in deep color or light color. This is how a black line on the white surface is detected.
The sensors are placed in a row a certain distance apart. According to their position, and which sensor's relative feedback signal, the color line follower can figure out the relative position of the line (middle, left, far left, right, or far right).
Connect modules together as shown below, making sure the Color Line Follower is connected to the front of the Chassis. Purchase our Car Kit if you would like to implement this project!
