Topic: Re: 2 Analogue Inputs To Create Differential Value (Read 114 times) previous topic - next topic



Just want to input the differential input  between two potentiometers (One reference and one feedback from a 12 V linear actuator. (will use a H-bridge BTN8982TA for arduino)
The aim is to have to motor turning clokwise and conterclokwise to locate the actuator in the right position.

However, the brige with the two potentiometer can return values from +5 V Maxi left , 0 in middle position and -5V Max Right. Relative voltage between the two potentiometes cursors

How is the Arduino going to deal with that?

Anybody have some answers?
