Firmware for the 30 RGB LED Xmas Star
The HEX file and Arduino sketch source file for the ATmega328P in the RGB LED Christmas Star.
The ZIP has been updated to also include a .HEX file to suit the ATmega88PB instead, as the TQFP version of the ATmega328P is hard to get (16/07/2021).

ATmega328P-AUR or ATmega88PB-AUR programmed for the RGB Stackable LED Star [1620920A.HEX or 1620920B.HEX]
An ATmega328P 8-bit SMD microcontroller programmed with the firmware to produce LED patterns for the RGB LED Star (1620920A.HEX).
Note that since ATmega328Ps are very hard to get, you might receive an ATmega88PB instead. It is programmed with a slightly different HEX file (1620920B.HEX) that does the same job on this processor.

Kit for the RGB Stackable LED Christmas Star
A kit of all the non-optional parts for the RGB LED Star including the PCB, programmed microcontroller and 30 RGB LEDs.
The microcontroller programming includes a number of patterns designed specifically for the Star. The LEDs have diffused lenses for improved off-axis visibility.
Note: photo shows assembled kit.
