MQTT Clock Display
Displays · Board: Pi Pico · Day 89 of 100
An LCD on the Pico W shows date and time synced over MQTT. Clocks that listen to the network.
How it works
Instead of NTP, this clock listens: a publisher broadcasts date and time over MQTT, and the Pico W's LCD shows whatever arrives. Any device on the broker can be the time source. Clocks that synchronize by subscription rather than by request.
What you'll learn
- MQTT time distribution
- Character LCD control
- Publish-driven updates
- Networked clock design
