# MQTT Servo Controller

Day 90 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

Position a servo from MQTT messages on the Pico W. Message-driven motion.

## How it works

Angle commands arrive as MQTT messages; the Pico W parses each payload into a target angle and drives the servo there. Command and actuator are fully decoupled — the publisher never knows or cares what hardware executes the motion.

## What you'll learn

- Message-driven actuation
- MQTT command parsing
- Decoupled control architecture
- Payload-to-angle mapping
