Hi,
I picked up a couple 0.1Ω 10w resistors to track current usage with an Arduino on a battery powered project but I don't have a precision ohmmeter, how can I extrapolate the resistance value? I only have a cheap multimeter and Arduino at my disposal and already I see a huge error ratio with the multimeter.
Thanks
