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 ...
Each Arduino capacitance test relies on a property of resistor capacitor (RC) circuits- the time constant. The time constant of an RC circuit is defined as the time it takes for the voltage across the ...
This code is used to display voltage and frequency measurements on an OLED display. The voltage measurement is done by using an analog input and a voltage divider circuit with resistors R1 and R2, ...
