Modify the code in index.js to quickly prototype your Neopixel patterns
without compiling and uploading to an Arduino board. It's pretty close to
real Arduino C syntax, so it's easily portable to the real hardware.
By default, the Neopixel simulator will generate a straight strip of pixels.
If you want to simulate a more complex layout, you can create the elements yourself
in src/index.html. The only requirement is that each pixel have the pixel class, and
a p-0 class (where 0 is the index of the pixel, incrementing).
Instead of new Neopixel(NUM_PIXELS) instantiate your strip with Neopixel.fromElement(STRIP_ELEMENT).
The Arduino constructor takes two functions: begin and loop.
begin is called once when the Arduino runtimes starts. loop is called
continuously. Unlike javascript, Arduino is synchronous and you call delay
to sleep between loop executions. In javascript, you need to use the await keyword
and the delay function on the Arduino runtime object.
