PING Sensor:

Time permitting, we will also start the discussion on the ultrasonic PING Sensor.

The PING Ultrasonic Sensor is one of the required labs you will have to perform before the end of the semester.

Here's the link to the PING Sensor from Parallax and here is the Chapter from the Smart Sensors Text using the PING sensor. These are the exercises you should perform when using the PING.
