Learning Math/CS/Engineering Design with Robotics
0.1.4. Key Features of the RoboBlocky User Interface
|
Objective: Learn how to test an ultrasonic sensor connected to an Arduino board that is connected to a Linkbot robot. Overview: The pre-placed code blocks initialize an ultrasonic sensor and use a loop to take five distance readings from the sensor at 2-second intervals. Run the existing code and place your hand (or an object) at different distances in front of the sensor--each time around the loop the sensor will calculate the distance to your hand and the code will print out the result. After you try running the code, modify it as directed in the Problem Statement.
