Can anyone help me

I'm working with a project and I need to get the temperature, for this I got a LM335, so my doubt is how to convert the value to digital. I got a friend idea of using a ADC0804 but I don't have idea how to connect them and how to use them, I'm kind of newbie... hope someone can help me.... thanks

There is an appnote /program written for it which is fairly straight forward. It·worked well for me, because I didn't have to write the code, I just used what·the good folks at Parallax provided.·

thanks guys, but I'm still with doubts... I would rather to use the lm335 and the adc0804 cause for the program is much easier I guess, so any other help will be good, thanks anyway

Hello,

·· If you're required to use those parts, it sounds like a class project.· In that case you might want to read the datasheets on each part, and look for code examples using the ADC0804.· Basically you're going to need 8 inputs on the Stamp just for the data.· Glancing at the datasheet, this looks like you're going to have some fun.· If it weren't for your part number requirements, I would've gone with the ideas suggested previously.· Or at least used a different ADC, such as the ADC0831.· Good luck!
