LED Matrix Clock
Displays · Board: ESP32 · Day 58 of 100
An ESP32 keeps a MAX7219 LED matrix showing internet-synced time via NTP. A glowing wall clock with zero drift.
How it works
The ESP32 pulls the current time from an NTP server, formats hours and minutes, and scrolls them across the MAX7219 LED matrix. Internet timekeeping means the clock never drifts and never needs setting — it just glows correctly, forever.
What you'll learn
- Large-format time display
- NTP plus SPI combined
- Scrolling text rendering
- Zero-drift clocks
