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 ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can bu… ...
