This article describes the implementation of a digital frequency meter using Arduino Uno to determine the sinusoidal frequency signal in the range of 20Hz to 5kHz. The logic involves counting the total number of pulses per second that appear at a digital pin of Arduino. The authors’ prototype is shown in Fig. 1. Block diagram […]
