When using a sharp ir distance sensor (analog), with arduino, can I use the same code as if I was using a potentiometer? Answered

With Arduino, can I use the sharp ir sensor (analog) with the same code as a potentiometer? If not could somebody give me a code example?


ASSUMING the output voltage of the Sharp is scaled exactly the same as the "potentiometer", yes, probably. Steve

It depends on if the output of the sensor is resistive or digital.

Generally yes - The sharp sensor will return a number between 0 and 255 which is proportional to distance. if you want to knw real distances you will have to scale the figures in software.
