Hello, first post here.
I am building a liquid submerged computer in a 26 gallon fish tank.
I want to use Neopixels as lighting on the underside of my custom built hood.
I plan on buying the 60 per 1m Neopixel strips. I will most certainly not use the whole strip, I just prefer that LED density.
I am guessing that I will probably only use about half or 30.
I have read that there is some memory concerns on how many pixels you can drive off of an Arduino. For space in the hood, I want to use the Arduino Micro. How to tell how many pixels I can drive with a Micro?
As for power, I will be using the 5v from the molex connector on the computer powersupply so this won't be an issue.

Neopixel 60 LED -1M

Please let me know if it would be viable to use these two products or do I need an Arduino Mega

Re: Arduino Micro Power Neo Pixels
I think I answered my own question. 3k is required per LED so just divide the amount of RAM by how many LEDs are going to be used.
Looks like I'll get a Mega2560.

Re: Arduino Micro Power Neo Pixels
Slight correction: it's 3 bytes per pixel. 1k of SRAM is enough for about 340 pixels.
