Now we measure the frequency by using Arduino and by using some mathematical calculation we can find the inductance or capacitance. We have used the given LC circuit frequency response formula. f=1/(2 ...

Along the way we will also learn how sound signals are received by microphone and how to measure frequency using Arduino. Sounds interesting right so let’s get started with Arduino based Home ...

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 study uses a Pierce oscillator because of the simple circuit, stability, and non-widening output signal for the quartz crystal frequency measurement. Therefore, the frequency measurement system ...

This code is a combination of two codes, one for measuring voltage and the other for measuring frequency. The voltage measurement is done by using an analog input and a voltage divider circuit with ...

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 ...

A method of measuring the resonant impedance and radio-frequency resistance of an oscillatory circuit, using a screen-grid tube, is described. It is based upon the principle of the dynatron oscillator ...

The range of the frequency to be measured by a measurement device depends on the purpose of performing the measurement. The frequency measurement device is built specifically according to its range ...

Yeah, if you are going to use a real Arduino and an LCD shield that is pretty expensive for a frequency counter. I’m not entirely sure what your requirements of reading 3 frequencies are.
