First project - lightning stick

What do you think? Be constructive please...first time I’ve ever programmed an Arduino...looked around at a few “lightning” ideas but either couldn’t get them to work or just plain didn’t like the effect, so thought I’d give it a go.

The LEDs are in a carbon fibre tube that I cut the lightning design into then refilled with polyester resin with glow powder and black pigment (so you can’t see the cutaway in daylight).

Same thing, but in daylight...
