or
- Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.
- Full-color module, Full color soft lights a lamp strip.
- WS2812B is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant curre-nt control part, effectively ensuring the pixel point light color height consistent.
- The data transfer protocol use single NZR communication mode.
- LED with low driving voltage, environmental protection and energy saving

Short answers for now: yes, an Arduino could easily run all these LEDs.
What I would suggest is using "addressable" LEDs. These are a type of LED that is connected in (one or more) a long strings (like a Christmas tree string of lights) and they can still be individually controlled--you can set any one of them to a desired brightness or color, while not changing any of the others. You need a micro controller to do that, and an Arduino Uno or clone can do that. You can buy a Chinese clone Arduino and use that; they are a lot cheaper than the official ones and they work just the same.
There is basically two kinds of addressable LEDs, designated by how many wires they need. The more-common group is 3-wire (there is only 3 wires connecting all of them) and the less-common group is 4-wire. The 4-wire is more stable in noisy environments, but I would guess that the 3-wire LEDs would work fine for this. A common type of 3-wire addressable LED is named 'WS2812B'.
Most of these kinds of LEDs come already soldered onto a little PCB or strip, and are too big to fit into your hoods.
The first addressable LED I would think of for this is the 5mm types that Adafruit sells-- https://www.adafruit.com/product/1938 --but they don't make those LEDs, so you may be able to find them cheaper elsewhere. Adafruit is kinda expensive.
You could also get the actual SMD addressable LEDs yourself, and work with them that way. Here is one source on Amazon(US) -- https://www.amazon.com/Led-World-WS2812B-Individually-Addressable/dp/B00YC7ZXRM ---these things are pretty small, they are only 5mm square, but they can be hand-soldered.
You need some libraries to get the Arduino to operate these LEDs, but the libraries are free to download and use.
Addressable LEDs usually run off of 5v DC, so you would want a power supply for that. I would suggest one that can put out at least 5 amps or so. This would be enough current to run all the LEDs, as well as the Arduino board itself. You can get power bricks that size (like the chargers that laptops use) or you can get metal-enclosure CNC-style power supplies also. Either would work here.
So, a bunch of these?
But what would they be attached to?
I picked up these from amazon. Not sure if it helps with shipping to Canada though.

coolcool thanks. So for hardware I would need: arduino/clone, addressable LEDs, and a power supply. im going to order this: https://www.amazon.com/Led-World-WS2812B-Individually-Addressable/dp/B00YC7ZXRM that Doug recommended. How about wiring/cables do those come with the LEDs? How does daisy chaining work? Are there and good beginners youtube tutorials or channels on this? Sorry I am completely new to this.
