NTP LCD Clock

Displays · Board: ESP32 · Day 93 of 100

Internet-synced time on an I2C LCD with the ESP32. Accurate clocks without extra hardware.

How it works

The ESP32 syncs with an internet time server on boot and writes the result to an I2C LCD in a clean HH:MM:SS layout. No RTC chip, no GPS module — just Wi-Fi and a two-wire display. Accurate time from almost nothing.

What you'll learn

  • I2C LCD control
  • NTP reliability
  • Clock display formatting
  • Minimal-hardware timekeeping
