Abstract

Digital Frequency Meter project is developed for the user to measure the frequency of an oscillator using LCD display. It consists of frequency sensor, Microcontroller unit and LCD display

The frequency sensor(Probes) are connected with the oscillator whose frequency is to be measured.

The input signal is given to the microcontroller through switching unit. The microcontroller senses the signal and counts the positive and negative pulse. It calculates the frequency per second.

The microcontroller sends the data to the LCD display to display the frequency of the oscillator.

This device is cost effective, portable and easy to use. Since microcontroller is used, the output will be more accurate
