LED Matrix Monitor 2

A customizable LED matrix display project using ESP32 and MAX7219 LED matrix modules. This project creates a "Matrix"-style rain effect combined with a functional digital clock that synchronizes time via WiFi/NTP.

LED Matrix Monitor 2

Features

  • Matrix-style falling characters rain effect with realistic brightness simulation
  • Real-time clock display with seconds progress bar
  • WiFi connectivity for automatic time synchronization with NTP servers
  • Configurable LED brightness levels
  • Multiple text display modes (scrolling, centered)
  • Modular code architecture for easy customization

Hardware Requirements

  • ESP-WROOM-32 development board
  • 4 MAX7219 LED matrix modules (8x8 each, cascaded)
  • Micro USB cable for programming and power
  • Jumper wires for connections
