2020 haven't been a load of fun, but at least it'll be Christmas soon - so why not celebrate by putting together an over-designed PCB tree powered by an Arduino Nano. Requires parts A, B and C in order to actually blink anything since the active parts of the electronics are hidden in the base (part C). The switch on this part is used by the Arduino sketch in order to change the way the LED blinks, but as the code is supplied you could always make it do whichever pattern you want.


A short video can of the completed project can be seen below, but note that the audio have been added in order to cover up the sounds of my puppy. Maybe I'll do a Christmas 2021 version with some sort of audio component, but that christmas is still more than a year away!
