If I wanted to sense a temperature and light 4 LEDs starting at temp
"x " (around 30c) and light a LED at "x or less" and 3 more in 1c
incriments, leaving #4 on over x+4 what is the easiest way to do it?
I an seeing a 339 and a buttload of resistors but I think I am working
too hard here.
I think you can adapt one of the bar graph chips to do this.

I love to cook with wine. Sometimes I even put it in the food.
