ESP32 LED Matrix: Multi-Function with FULL WLED and more!

In this video, I'll cover the build of my upgraded WS2812b-based LED matrix using two ESP32 based controllers. Unlike the prior version, this one does not require Home Assistant/MQTT for control, but an API allows optional integration if desired. Some features of the matrix include: • Clock in 12 or 24 hour format • Indoor and/or outdoor temperatures • Scoreboard with customizable team names • Countdown timer with optional buzzer • Text with multiple display modes • Full WLED secondary controller with auto-switching • Complete management and customization via web app • No third-party automation systems required! • API for _optional_ integration with external systems, like Home Assistant You can find copies of all diagrams, complete part lists and additional build details in the related written guide: https://resinchemtech.blogspot.com/2025/01/matrix32.html Github repo with firmware and full wiki: https://github.com/Resinchem/Matrix-Clock-ESP32 Chapter Links: ============= 00:00 Intro 00:35 Original Build Limitations 01:40 Key Features 05:36 Parts 08:32 The LED Matrix Display 12:30 The Primary Controller 15:30 The Control Box 17:55 The Secondary (WLED) Controller 20:47 The Frame 24:13 Component Install and Wiring 27:44 Power Distribution and Safety 29:03 Firmware Install and Onboarding 33:18 Initial Settings 35:01 The API and Home Assistant 36:09 Additional Information Parts Used or Shown: =================== This is only a _partial_ list of the primary parts used.
