The circuit is simple. Point the “-” pin on the RGB LED module to the Arduino’s GND pin. If you align it right, the other three pins should enter pins 13, 12, and 11. Making It Work. Once you’ve ...

That's why I came with the shift register 74hc595. We need only 3 Arduino digital pins to control as many LEDs as you want. All you need a shift register ic. THere is 12 RGB led with 20 effects.

[Sayantan Pal] did this for the humble RGB LED matrix, creating an extra-thin version by recessing WS2812b NeoPixel LEDs inside a PCB. The popular WS2812B is 1.6 mm in height, which happens to be ...

This is a tiny and clearly arranged Arduino library for the basic RGB LED functions, to easily drive an RGB color LED (common anode/common cathode) and mix the colors. It uses the principle of ...

I have made RGB Goggles using WS2812B LEDs and Arduino Nano. The Arduino based Goggles have many different color animations that can be controlled using a mobile app. The app can communicate with ...

An Arduino turning on and off a LED, how original. Why dont you guys throw it on top of the pile of 1000 other Ardunio+LED projects you’ve shown here. inb4 b-b-but its network controllable.
