This part number (and ofcourse the LED type) is not very critical. If you want to use a bi-polar transistor, don’t forget to add a resistor (~1KΩ ) between Arduino D10 and the base terminal of the ...

The system takes continual screenshots and averages the pixel colors before sending the data to the Arduino over USB.As with the audio ambient lighting, using pulse-width modulating each channel, the ...

A case will protect your Arduino and ensure your sweater has the chance to light up the room for many holidays to come.

The Arduino-powered display is built from a strip of 35 RGB LEDs. Now, that’s four pins per LED but one of is ground, leaving just 105 pins that need to be addressable.
