 +====== Controlling WS2812B LEDs Using an Arduino (Part 1) ======
 +
 +
 +In this video, I explain how pixel addressable RGB LED's such as the WS2812Bs work, and how you can control them from an Arduino using the FastLED library. I show how to install the FastLED library as well as get started using it with some demos. I go over the advantages as well as limitations of addressable RGB LED's and how we interact with them (data vs clock+data, etc). 
 +
 +This video is the first in my 2 part series on using WS2812B LEDs with an Arduino.
 +Next video will be on writing your own programs and patterns using the FastLED library to control the LEDs, rather then just demos to get up and running.
 +
 +Components used:
 +- Generic WS2812B 30 LED/m strip
 +- Generic Arduino Uno with Atmel 328p
 +- FastLED library
 +
 +I won't add any links for purchasing, this video is not sponsored and all components were supplied by myself, but make sure you choose a reputable source for parts!

 +If there are any mistakes or bad practices I mentioned in the video, please leave a comment and I'll try to pin a compilation of updates.
 +
 +Production rants/remarks:
 +
 +- Sorry for the buzzing microphone through part of the video. I tried using a shotgun microphone for the first time rather then my jankier previous setups, and the combination of zipties to mount the microphone the tripod, and noisy circuitry in the dummy battery I used made it come out buzzy.
 +
 +- Filmed on a Sony SLT-A33 (and Samsung MiniDV camera). Takstar microphone for A footage, and Fifine condenser microphone for all software shots using OBS.
 +
 +- A33 does not have a clean HDMI output, so we're stuck with the aperture and shutter speed with the HDMI capture card... (It also doesn't read the sensor at full-res unless filming, but then it overheats)
