Sensors expedition: Mission 5 of 6

Color Coded


Intermediate

1 hour

Grades 3 - 8

MISSION OBJECTIVE

Learn to create a secret coded message with color.

Help Piperbot and Pip get into Maker’s City by decoding the color sequence from the color wheel. Ask: “How does the Color Sensor interpret color from light that bounces back to the sensor? Can it tell between different shades of the same color?

MISSION RESOURCES

Learning Goals

  1. Students will use the Color Sensor to “read” and report colors and to map colors to different words/letters to create a secret code to share.
  2. Students will understand the coding elements of if/then statements and interface with the Color Sensor using different graphical views on Piper Make.
  3. Students will understand the fundamental concepts of how they perceive color in the world around them.

Troubleshooting Tips

  • Is the Color Sensor not detecting color?
    • Ensure that the Color Sensor is on. A small switch on the Sensor must be on for it to work (you will see a white LED turn on when this is correct).
    • Ensure that you’ve plugged the wires into the right GPIO. Look at the Digital View to see which pin you’re affecting.
  • How does the Color Sensor work?
    • Color Sensors emit a white light and then measure the red, green, and blue wavelengths that bounce back. Based on the amount of red, green, and blue light that bounces back, we can figure out what color the Sensor looks at.
