Recently I have been trying to get a Fallout 4 style compass in processing 3 to show wind direction for a Weather station for my arduino. I was just woundering the basic function code and some of the style. Thanks.
As well as woundering if i could do some thing like this-----> https://learn.sparkfun.com/tutorials/addressable-rgb-led-music-and-sound-visualizer
but instead of a sound detector i would like it to be a mp3 sheild. thanks
