Re: Help wiring potentiometer-to-Analog port
Hi, This potentiometer acts as a variable voltage divider. So if A=0V and B=5V then if the slider is nearest A then C will give a reading near 0V. If the slider is nearest B then C will give a reading near 5V. If the polarities were switched such that A=5V and B=0V then C will give 5V when it is nearest A and 0V whereas it would read 5V if it is nearest B. Of course anywhere in between you will get a reading at C between 0V and 5V. Hope this helps!
