I just completed my adjustable grill block which closes/opens based on wind speed (now that I think about it, a strong headwind could mess things up)... The reason I did it this way though is because I am not familiar with the electronics needed to do what you are working on. Mybe I will try to alter mine when you get yours completed (maybe with a How-To?). This is a great idea and I hope everything ends up working out for you. I look forward to seeing the end result.
