How to simulate a DC digital ammeter in a program?

Question

Electronics

What elements and blocks can be used to create a digital DC ammeter? If you can help with the diagram and calculation it will be generally cool

Answer 1

Depends on the range of the measured current and the measurement accuracy.
There are ready-made modules. If for Arduino, then ACS712. Pretty inaccurate. I do not remember the discreteness, look on the Internet.
And the easiest way is a low-resistance shunt in front of the load, and measure the voltage drop across it. That is, a voltmeter to measure current. Instead of a voltmeter - an analog input of the ADC.
