The circuit diagram of the digital frequency meter is shown in Fig. 3. It consists of Arduino Uno board, optocoupler MCT2E (IC1), 16×2 LCD and a few other components. The sinusoidal signal whose ...

The signal whose frequency is to be measured is applied to test signal input terminals, as shown in the transmitter-side circuit diagram (Fig. 5). In this frequency meter, test signal must be an ...

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 ...
