(D6 of Arduino connected to Din of WS2812B) It is highly recommended to connect a 100nF capacitor across the ‚5v and Gnd‛ connection, and a 100-470 Ohm resistor in series with the ‚Din‛ line of the ...

To drive the LEDs, [Ole] is using an Arduino. Even though the WS2812s are individually addressable and only one data pin is needed, [Ole] is using five individual data lines for this matrix.

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

In this project, we're making a cool 4×4×4 LED cube with Arduino Nano. LED cubes, also known as LED Matrix, can light up your room, study space, or Maker area giving it a awesome cool look. Moreover ...

But if you would really like to build a tree ornament with addressable LEDs, then check out the Sierpinski Christmas Tree which can be cascaded to form an array of tree ornaments.
