Introduction to Robotics/Sensors/Lecture/Teachers

We will be using the ultrasonic sensor to measure distance. The ultrasonic sensor uses sound waves to determine the distance to an object. The waves travel from the emitter at the speed of sound until they hit a distant object. The sound waves bounce off the object and are detected by the sensor. The sensor measures the amount of time it took to hear the echo. It will be your job to convert that time measurement into a distance measurement.
