ABSTRACT: This paper presents the design and implementation of a low-cost digital frequency meter capable of measuring the frequency of periodic signals ranging from a few hertz to hundreds of kilohertz. It is designed using basic electronic components such as a microcontroller (e.g., ATmega328P), a crystal oscillator for time reference, and a digital display unit. The proposed system uses the time period method to count signal pulses over a known time window, thus enabling accurate frequency computation. This cost-effective and compact design can be used in laboratories, workshops, and educational environments where budget constraints exist.
Keywords: Frequency Meter, ATmega328P, Microcontroller, Digital Measurement, Timer, Oscillator.
