STROBO CONTROLLER & just a square wave 5V generator (20ms)

Hi! Here I present to you the STROBO ctrl! It’s literally a box made with a 3D printer, with an Arduino inside, battery-powered, and packed with a bunch of features that let you control your strobe light through a 6.3mm mono TS jack output! At its core, this is essentially a 5V square wave pulse generator with a duration of 20ms. Manually (using the big knob), you can set the rate from 0 pulses per second up to a maximum of 20 pulses per second. I won’t go too deep into how it works here, because there’s a dedicated video on my YouTube channel—I'll leave it for you down below! https://youtu.be/SnG-ElnxRpg
