How can i tell the value of a potentiometer

Web23 de fev. de 2024 · Basically I have to follow the resistive value of a potentiometer that moves from 0 to 500 Ohm doing from 0 to 360 degrees and vice versa. The potentiometer moves slowly, makes one revolution in about 1.3 minutes. I would like the stepper motor to track the movement of the potentiometer as it changes its value. WebSince we have our readings, we need a way to convert it to a brightness value for the LED. By using analogWrite (pin, value) we can tell the LED how bright to be. analogWrite only works on pins 3, 5, 6, 9, 10, and 11 on the Arduino Uno so make sure your LED is connected to one of these pins. These pins are indicated by a squiggle line next to ...
