Week 3 - Day 3

On day 3 we introduce conditional statements and learn about how a robot uses it sensors to detect light and sound and use those phenomena as information.  Campers program the robots to stop and turn using the ultrasonic sensor and the color sensor.  We learned about the nature of waves and frequency using different-colored Slinkys to show how the robot's sensor differentiates color.  At the end of the day, we asked "What if we want the robot to keep going?" Tomorrow we'll learn about loops...
