MQTT Joystick Controller
Wireless · Board: Pi Pico · Day 86 of 100
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
