Abstract:The article presents an experiment for studying the Doppler effect using the Arduino sensor integrated with LabVIEW to detect the frequency of the rotating sound source. A mobile phone application is used as a sound generator emitting 500–1100 Hz frequencies and rotated in a uniform circular motion. The Arduino sound sensor is affixed at rest, acting as a listener to observe the frequency of the mobile phone moving toward and away from it. This experiment can express a significant concept of the Doppler effect… Show more
