8×8 RGB Led Matrix with WS2812 driver with Arduino Uno
In this video we learn how to use this 8x8 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. 8x8 RGB Led...
