jollifactory @ instructables.com has published a large 8×8 LED Matrix Display which is driven by a MAX7219 and Arduino. For this project, we will be building a single color large LED matrix display which is made up of a few large 8×8 LED matrix modules daisy-chained together. Each of these 8×8 LED matrix modules is around […]
8×8 RGB Led Matrix with WS2812 driver with Arduino Uno
https://www.electronics-lab.com/8x8-rgb-led-matrix-with-ws2812-driver-with-arduino-uno/
In this video we learn how to use this 8×8 RGB LED matrix. This matrix is using the WS2812 driver and it is great, because each LED is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED. 8×8 RGB Led Matrix with […]
