In This Lesson I will explain how to Design Resistor Meter (similar to Fluke).
This is done by These simple steps:
1. We have a “Known” Resistor – that we know exactly what is its value
2. We connect a simple Circuit like This: VCC -> Connect to Resistor we want to measure -> connect to Reference Resistor that we know its value -> Connected to Ground
3. Analog to Digital Arduino input is connected between these 2 resistors.
4. We measure the voltage between these 2 resistors (of-course this voltage is changing according to the resistor that we want to measure)
5. By all this information we Can Calculate the Resistor.

The 2 Formulas to Calculate the Resistor are:
1. V(measured) = [ADC(VALUE)*VCC]/1024
2. R(measured) = {R(Known)[VCC-V(measured)]}/V(measured)
