MCP3201 12bit ADC·· "got this working"
LM358A· Op-Amp· "Have no clue how to setup the resolution"

Thermo resister is about· 0 ohms @ 70c·· to about· 12k ohm @ ·25c· on 5v

I got the ADC·working but no luck on setting up the·OpAmp to get the·5v / Thermo Resister resolution setup right to use the full 4096 scall of the ADC.
