Abstract: In this study, the Arduino is used to build a low-cost data acquisition card with its sampling frequency of up to 50k Hz, so sampling frequency can also be applied to adjust the signal ...

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

This project demonstrates how to control the frequency of a buzzer using push buttons with an Arduino. The buzzer frequency can be increased or decreased by pressing the respective buttons. The code ...
