MicroPython Analog Input Examples

This directory contains MicroPython examples related to reading analog inputs.

Contents

ADC - Read analog voltage on an ADC pin
Smoothing - Read analog value with smoothing

Requirements

MicroPython board
Analog sensor like potentiometer
Jumper wires
Breadboard

Usage

These examples demonstrate:

Reading raw analog values (0-4095 range)
Converting value to a voltage based on ADC reference voltage
Smoothing readings using a running average

To run

Connect analog sensor to ADC input pin
Modify pin number as needed
Upload code and view serial output
Rotate potentiometer to see changing values

Notes

ADC pins vary across boards - use a labeled ADC/analog pin
Adjust voltage conversion for different ADC refs
