This is one of the easiest ways to include a lot of controllable RGBs LEDS into your Arduino or other microcontroller project.
This panel is based on the new WS2812B IC, each of which contains a really bright RGB LED with built-in LED driver circuit. The cool thing about these LEDs is that you get to control the color and brightness with only one data pin. As these are chainable to each other, you need only one pin on your Arduino to control the entire panel. Data flows from one LED to the next through the DIN/DOUT pins on each LED.
Each LED can support 256 levels of brightness and 16 million colors with a scan frequency of 400 Hz.
This is a 12x12 LED panel (with a total of 144 LEDs) within a square of size 96 x 96 mm, thats 144 LEDs in an area of about 92 cm2.
These panels are fully compatible with Adafruit's Neopixel and Neopixel matrix libraries for Arduino.
Note: This panel would require a power supply of 5V/4A to operate comfortably.
