DIY Voltmeter with ESP32 and MicroPython
In this video you will learn how to build a simple #Voltmeter using an ESP32 and #MicroPython
The aim of this project is to show how to read and plot analog input voltages.
In this example, a potentiometer is connected to the input of an #ADC channel. The voltage at the potentiometer arm is displayed as well as plotted on the Thonny screen as the arm is rotated.
This example is taken from the MakePython ESP32 Development Kit by #Elektor.
