Plan not to loose more than 50mV from the source to the LED matrix. So that would be 50mV / 3.5A = 14 mΩ. For both supply wires, so 7mΩ each trace. A 1mm² copper cable has about 17.5mΩ/meter, so you'd ...

The PCB was developed to control any addressable RGB LED strip that uses WS2812B or similar LEDs that take 3 inputs (VCC, GND and Data/DIN) using any DIP8 packaged microcontroller. All board traces ...

LED Music Spectrum generates the beautiful lighting pattern according to the intensity of music. It contains many RGB LEDs which not only turns on and off as per the music but also change color ...

Here, RGB LED light intensity and colour change with the rhythm and volume of music. It is a great idea to have such a lighting system at home, gym or music school. This circuit is based on ATmega8A ...

[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 ...

[Stan] built this LED matrix using a 16×16 grid of RGB LEDs. He built the hardware and wrote some subroutines to randomize the colors. He’s not using PWM because frame buffering is not f… ...
