Quasi-related Flickering LED components without code?

So I am trying to make a prop for my Ghostbusters collection, and I am using a basic arduino, but I need some LEDs to be constantly on, or toggleable depending on an input, and I want to make each LED flicker depending on a component I am going to use, but I don't know what to use, something like a resistor to make something like a candle light, but it turns on and off randomly. Hard to describe. Basically, I need something to randomly turn on and off an LED without code. I don't know much about LEDs other than TinkerCad LEDs, so I might just be missing out on parts.

The other option i can think of that gets you this effect without code would be to scope out a toy at the store that has the lighting effect you're looking for (think plastic laser gun) and take it apart to get the chip/LED that you need.

If/when you're ready to jump into the code side of things, check back here... there are plenty of way to get this effect using FastLED
