Addressable LEDs are magnificent. One of the first things I do to test them out is to assign pseudo-random colors. My code converts a number from zero to a maxBrightness value into a three-value array.
Light panels lit up
The problem with my arrays is that I connected them at a 90° angle rotated clockwise. I figured I could mathematically fix this issue, and I sketched out an equation that would accept an X and Y value then convert them into an LED address.
Calculations to overcome rotated panels
My next step was converting the equation to code and verifying that it worked. I tested the function by turning on the lights horizontally, starting with the upper left and moving across, then down.
Lighting up in the right order
All my hardware was connected and tested, so I started looking at incoming data. I first needed to recognize the tempo, but I'll need to correct issues with my incoming time pulses. I tried to ignore missing pulses by code trickery, but it was not fruitful.
Clock signals and hiccups
I used my X-Y coordinate function to toggle the first row of lights. Sixteen buttons control the middle light columns, with four on the left and right as a buffer area. The borders will eventually serve as indicators for the selected track.
Toggling a couple of notes
I programmed most of the other function buttons, so now I can select which row my note buttons will change. Most notably, I wrote code for the randomize button that creates an arrangement based on the velocity slider. If the slider is low, it generates a few notes, but a lot when high.
Pseudo-random notes on all tracks
