Variable temperature controller

Arduino-based temperature controller with variable rate temperature change. It will hold an initial temperature for a specified amount of time, and will then ramp that temperature up or down, and hold at a final temperature. For example: heat a water bath for chocolate to 130 and keep it there for 10 minutes (assuming it will take that long to melt all of the chocolate). Then reduce temperature by 1 degree every 10 seconds for 40 iterations, and keep at a tempered 90 degrees until you power everything off. Many cheese making recipes specify heating from X to Y at no more than 1 degree every minute, so this is perfect for that. No more hovering over a water bath for hours!
