Fibonacci 182 Card is a beautiful credit card sized rectangle with 182 RGB LEDs surface mounted in a Fibonacci distribution. Swirling and pulsing like a tiny galaxy, it’s mesmerizing to watch.
It consists of 182 WS2812C-2020 RGB LEDs, arranged into a circular Fermat’s spiral pattern.
It has solder pads on the back that match the pinout of the QT Py by Adafruit, or XIAO by Seeed. It can be used by any microcontroller via the 5V, GND, and Data In pins. It also has a Data Out pad, for connecting more LEDs on the same data pin.
The six mounting holes are surrounded by capacitive touch compatible pads. They’re connected to the A0-A3, A6 & A7 pads/pins on the QT Py footprint. The SAMD21 QT Py supports capacitive touch on these pins.
