DAY 3 · DO
Color Sensor Mission
Build the route, collect actual results, and show how the sensor changes the robot's behavior.
TOPIC
Color-sensor control
OBJECTIVE
Students will build and debug the green-to-red Sphero route.
DEMONSTRATION OF LEARNING
Students will submit route evidence, code evidence, test results, and a systems explanation.
Core steps
- Build a green-to-red route with the cards about 18 to 24 inches apart.
- Use roll and delay blocks to stop on each color.
- Add a one-second start delay.
- Place the total color sensor block inside a main LED block after each stop.
- Test, record the expected and actual LED color, and revise the route or code.
Optional extension
Continue the official Sphero lesson to add color events, a red stop sequence, direction controls, or a color-boundary challenge.
Turn in
- Photo or short video of the route
