Servomotor controlled by Potentiometer using Arduino - Wired Connection


Circuit Diagram:


Required Components:


Arduino uno/nano - 1 Nos
Battery - 1 Nos
Servo Motor - 1 Nos
Potentiometer - 1 Nos

Program Code:

#include <Servo.h>

Servo myservo;  // create servo object to control a servo

int potpin = A1;  // analog pin used to connect the potentiometer
int val;    // variable to read the value from the analog pin

void setup() {
  myservo.attach(6);  // attaches the servo on pin 6 to the servo object
}

void loop() {
  val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023)
  val = map(val, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180)
  myservo.write(val);                  // sets the servo position according to the scaled value
  delay(15);                           // waits for the servo to get there
}
