You can create a voltage divider , using two resistors, to make a 3.3v source from the 5v on the Arduino mini. Check out the section on level shifting in this SparkFun tutorial on voltage dividers: https://learn.sparkfun.com/tutorials/voltage-dividers/all?print=1 By the way, precisely which Arduino ...
I assume you plan to drive the strip from a microcontroller, like Arduino. The most common addressable strips in use now (2018) are WS2812 ones, powered at 5VDC , with 5V logic, as well. There's lots of sample code for them. Here's one such strip: https://www.sparkfun.com/products/12027 And here's a...
