Summary of D.I.Y SMART RGB MATRIX 8×16
This project demonstrates how to build an 8×16 RGB LED Matrix using Arduino Uno or Nano. The matrix can display scrolling messages, animations, and music volume visualization. With NodeMCU integration, it can also show weather information or interface with Ethernet PLC systems. Various tests include auto-rotate message display using a gyro sensor, animation, VU meter audio visualization, and smart display examples. The article provides detailed component lists and tool recommendations to help users create their own customizable RGB LED matrix screen.

In this project, I’ll show you how to make your own 8×16 RGB LED Matrix using Arduino Uno/ Nano. An LED Matrix can show scrolling messages, display animations, music spectrum analyzer … With integrating NodeMCU, it can be used as small screen to show weather information from internet or any process values when it connect to Ethernet PLC system.
So, let’s watch my videos below and follow my instructables to start with building your own RGB LED Matrix.
- Auto-rotate scrolling message test (update on November 6th, 2018): Using MPU-6050 with Kalman filter to calculate the angle when we rotate Led Matrix.
- Animation Test
VU meter test: It shows music
volume unit by using fix FFT transformation. Led Matrix will be connected to music player by audio jack 3.5mm.
Smart Display Test: Connecting to PLC system
Smart Display Test: Showing weather information from Internet
