# MQTT Joystick Controller

Day 86 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

A joystick publishes MQTT messages visualized on a Node-RED dashboard. Real-time control streams, wired or wireless.

## How it works

Joystick positions are encoded as MQTT messages and published continuously; a Node-RED dashboard subscribes and visualizes the live stream. The joystick becomes a networked input device — its movements observable anywhere the broker reaches.

## What you'll learn

- MQTT telemetry streams
- Input data encoding
- Real-time control data
- Networked input devices
