Good luck ! But is too much trouble for a such simple machine as a popper.
Playing these days with a Fresh Roast wannabe chinese machine, I can tell you that a simple "profile" as: start at 50%, switch at 1:30 to 60%, then start at minute 3 to 75% and let there to the end, gives identical results as the most sophisticate profiles.
Connecting a computer for such task is just... more love for tinkering, than for roasting and enjoying coffee
