  • Yes, your intuition is good. The first three bytes control respectively Red, Green and Blue for the first led, the second three do the same for the second, and so on.
    I'm also developing some stuff by controlling leds, something that could be best defined as a software defined lamp; Depending on what you actually want to achieve, you could be better off using the graphics library (useful if you need to draw a line or something like that);
    I suggest you attempt to do something on the espruino command prompt, I love it because it allows for very rapid prototyping and gets you going quick.
    I include the file I'm working on; Probably not all of this is working, and some comments are in italian, but you could draw some inspiration as I use a few different ways of accessing the led array.
