Lesson 7: Controlling 3 LED with a Potentiometer in Micropython

This tutorial covers using a potentiometer to control three LEDs (green, yellow, and red) with the Raspberry Pi Pico W:

• Homework Solution Review: Recap of connecting a potentiometer and three LEDs, mapping readings from 0 to 100.

• Circuit Setup: Wiring diagram for connecting the potentiometer and LEDs to the Raspberry Pi Pico W.

• Reading and Mapping Values: Reading analog values and mapping them from 432-65,535 to a 0-100 scale.

• LED Control: Using if statements to control LEDs based on the potentiometer’s position (green for 0-79, yellow for 80-94, red for 95-100).

• Practical Demonstration: Showcasing the circuit and code in action.
