Exploring kinematics graphs using Arduino and an interactive Excel spreadsheet

We present a low-cost apparatus using Arduino and an ultrasonic distance sensor that permits students to learn about motion graphs more intuitively. Using an interactive interface built using Excel and an add-on, the students can see a graph of position or velocity as a function of time. They are invited to reproduce the proposed motion graph moving themselves in front of the sensor. The Excel spreadsheet presents a real-time of their movement together with the reference.
