Measuring Speed of Sound With HC-SR04 Sensor

Learn how to measure the speed of sound using an HC-SR04 sensor and an Arduino in this 29-minute tutorial. Build upon the circuit from the previous lesson to create a practical demonstration that combines electronics with physics principles. Practice dimensional analysis and unit conversion skills while calculating the speed of sound in both metric and imperial units. Follow along step-by-step to set up the experiment, collect data, and perform the necessary calculations to determine the speed of sound in your environment.
