The Arduino Digital Multimeter/Oscilloscope app is a handy tool to measure voltage, current, and other physical parameters. It can also generate and record sine and square wave sounds with adjustable frequencies and amplitudes.

With the help of this app, you can measure:

The voltage and current strength and value of the electrical current in the circuit.

The resistance of the circuit.

The sound generated by the sound generator.

The frequency and the amplitude of the sine and square wave.

The value of the capacitance of the circuit.

The resistance of the circuit, the sound, and the frequency are measured in units of resistance, voltage, and current, respectively. The value of the capacitance and the inductance are measured in units of microfarads and nanofarads, respectively.

This app can also measure the value of the physical parameters in real-time. The data measured are displayed in real-time, and you can also record and share them.
