Lesson 5: Reading Analog Voltages Using a Potentiometer

This tutorial covers reading analog voltages using the SunFounder Kepler Kit for Raspberry Pi Pico W:

  • Analog Voltage Reading: Importance of reading analog voltages for sensor inputs like potentiometers.

  • Wiring Setup: Explains connecting a potentiometer to Pico W, including ground, 3.3V, and GPIO pin 28.

  • Code: Write Python code to read and print analog voltage values using GPIO pins.

  • Conversion: Convert ADC values to voltage (0-3.3V) using a linear equation.

  • Demonstration: Show code reading potentiometer values and converting them to voltage.
