One of my first projects. An Arduino Ohmmeter.

Measures the resistor value and displays it on a LCD Display.

I really like it, and I have a suggestion: you could implement an automatic range finder. You only need several resistors for the potential divider. Maybe its possible to drive a CMOS4066 to select the right resistor.
Sorry for my bad English...

Thats a good suggestion. The more the two resistors have the same value, the exacter is the result.

Hi,

May I know what range and sensitivity can I expect from that setup?

Thank you.
