The following gives you a very brief introduction of the workin principle of the low-cost, but versatile LED Matrix. In our version we used the Neopixel Matrix, others might work also.
It can be controlled with an ESP32 or Arduino. The code relies on the Neopixle library, provided by Adafruit Arduion IDE - further information available here.
- 8x8 RGB LEDs
- 5V Control Voltage
- WS2812 LED controllers
This is how it looks like in a cube
GND == GND
5V == 5V
DIN == 26
The code can be found in the Software GIT.
Unplug the power supply when you're not using the LED Matrix!
