# RGB Color Mixer

Day 6 of the 100 Days 100 IoT Projects collection. Board: ESP32.

Three potentiometers blend red, green, and blue channels on an ESP32-driven RGB LED. A hands-on way to learn multi-channel PWM.

## How it works

Three potentiometers feed three analog channels, one per color. Each reading sets the PWM duty of the red, green, or blue leg of the RGB LED. Because the channels mix additively, every knob position produces a different blended color.

## What you'll learn

- Multi-channel PWM
- Additive color mixing
- Parallel analog inputs
- Mapping inputs to outputs
