Ok, so before I go into this I will admit that I've read so many different possible solutions to this that I think Id have more luck designing a new hotdog. There is a reason I'm a programmer first and a circuit guy last.
What I am trying to build is a circuit that lights one of 5 LEDs based on temperature (figured based on reading that means the LM35 and LM3914?). The LEDs I need to display represent the following temperature ranges:
<0C = White
<=0C to 25C = Blue
>=25C to < 50C = Green
<=50C to < 75C = Yellow
>= 75C = Red
My supply voltage is 24VDC. And what I'm looking for is what I read is being a "dot" solution. As I said, there seems to be a lot of "suggestions" out on Al Gore's Amazing Internet. But none seem to have the input voltage range I have. Can anyone point to a references that might help?
