Do you want to learn how to build a voltmeter in Python? This tutorial will teach you how to do that, and show you how to incorporate your phone into the project.

Thanks to the Zerynth App you’ll be able to read the results straight from your phone.

The project is divided into three parts:

  • Reading the output volt over the console.
  • Transform the project to a higher level by reading the result wirelessly using Zerynth App.
  • Advance the data reading using a graphical interface from “jqxKnob” element of the JQWidgets.

Reading the results on your phone with the App

Once you’re done with the first part, you’re ready to bring your project to a higher level. Read the results wirelessly over the Zerynth App.

So, enable WiFi on the ESP32, connect it to the Zerynth App (which you can download here), and follow the rest of the instructions in the tutorial.
