Analogue Sensors – Calculate the Nonlinearity Introduced by a Load or Pull Down Resistor

Have you ever had that terrible feeling that adding a load resistor or ‘pull down’ to your sensor is messing up all your analogue readings? Maybe you’re wondering why we’d want to spoil a perfectly good circuit by putting in a load resistor at all? For many years I found that I would get strange, […]
