On this page you will find Phyduino experiments on mechanics. For each experiment there are instructions (PDF file), a list of parts, the sketches used and, where applicable, files for printing housings.

Experiments with the ultrasonic sensor

According to the manufacturer, the HC-SR04 ultrasonic sensor can be used to take measurements in the range between 2 cm and 3 m with a resolution of 3 mm. A measurement requires 20 ms, so that a maximum of 50 measured values can be recorded per second.

The sensor instructions explain how the ultrasonic sensor works in more detail. The installation of a sensor in a housing that can be produced using a 3D printer is also described.

The "Vibration analysis", "Free fall" and "Running functions" instructions describe three examples of using the ultrasonic sensor in physics lessons.
