I should make a stroboscope with control using a potentiometer, utilizing a UV LED strip for a Time Fountain project. I would appreciate the components and a schematic if someone has done something similar before..
Strictly speaking the way you described what you want you don't even need a microcontroller. A classic generator with a 555 timer chip should work for you. Or are you not telling us everything and will start adding different details later?

What I'm actually most interested in first is which UV LED strip to order and from where, one that I will be able to adjust the flashing frequency quickly or slowly enough to achieve the effect of a levitating water droplet. I would like to control the frequency using an Arduino because I already have an Arduino Uno, and it's convenient since this will be a school project where the kids are already working with Arduino.
Do you have a UV sensor that will tell you then the UV LED strip is on and when it is off? Obviously your eyes cannot see the UV light.

Apropos.
I think the OP wishes for a "blacklight" experience.
- UVA – This is the range from 400 nm to 315 nm. The so-called “black lights” that are used for eerie lighting effects fall into this range. UVA is not absorbed by the ozone layer.
The Time Fountain will be performed in the dark with fluorescent liquid, and the UV LEDs will only enhance the desired effect.
Are you also going to do all the program development and testing in the dark? Think about using normal visible LEDs for that and change at the last minute for a final test in the dark.
UV LEDs:
Ultraviolet light can be generated by some light-emitting diodes, but wavelengths shorter than 380 nm are uncommon, and the emission peaks are broad, so only the very lowest energy UV photons are emitted, within predominant not visible light.
UV black light (390-400nm wavelength)
All LEDs are generally very fast. Rather, you should think about the circuit itself for fast switching on and off by choosing a suitable MOSFET and possibly a driver for it. When it comes to fountain and water drops I don't think you need very high frequency. Do you at least have an idea what frequency you need for the strobe?
No, I don't have an idea, that's why I asked someone with experience, so that I first know the components I will buy, and later I can experiment with frequencies.
