This is a complete guide of measuring voltages with ADC pins of the ESP32 microcontroller. Precision measurements are very important to us, because our future experiments and hardware development efforts will depend on it

Collect the data from one or multiple devices and monitor them via your browser.

Requirements: Arduino IDE Installed. In order to proceed you need to have installed the latest version of the Arduino IDE. If you already have an older version , uninstall it and download the latest one. Otherwise it may not work.

In this article, I am going to demonstrate you installation process of the driver for the CP210x family of USB to UART bridge chips. A lot of ESP32 development boards is using this chip to support USB communications.

Step 1: You need to google for a driver. Just type in “Arduino Nano CH340 Drivers” and many links are going to pop up.
