TUTORIAL: How to Make a High Precision Current Shunt Monitor - Arduino! (Part 2/2)

Resistor network calcs: We want to replicate 75mv... We have 5000mv from Arduino. If we divide 5000 by 75 we get 66. So 75mv is one 66th of 5000mv. Therefore we use a potential divider of two resistors with values 1:65. Because my slider is 5k, the other resistor has to be 65 times greater value, which is 325k.
