    Arduino Ohmmeter

    This is an interesting topic and I thank you for sharing - I look forward to trying this myself in the near future. One thing I noticed is that the equation states one format but then the actual calculations performed at different.Equation stated:(Rx)ohms = 10k * A1 / (A0 * 2) - A1However it is worked out as the following:(Rx)ohms = 10k * A1 / ((A0 * 2) - A1)Order of operations would say that 10k * A1 / (A0 * 2) would be calculated before subtracting A1. Which is correct?
