Printer-friendly version
This Unit introduces students to both the Ultrasonic Sensor and Color Sensor. The Ultrasonic Sensor uses sound waves beyond the human detectable range (ultrasound) to measure the distance to objects, while the Color Sensor uses visible light waves to determine the color or brightness of a surface. Now equipped with all 4 sensors, students can revisit the Parking Lot 3 scene with new approaches and take on a timed line following challenge.
