Control Servomotor Using Potentiometer & Arduino Uno

Hello Friends welcome back to Techno-E-Solution, In this Video I'll show you how to "Control Servomotor Using Potentiometer & Arduino". In robotics servomotor is essential there are many applications of servomotor in robotics. So in this tutorial we how to connect servomotor to Arduino & control it using potentiometer . How it works ? Basically when potentiometer increases gradually Arduino read it's value & send output to servomotor & servomotor rotates gradually like potentiometer. So without wasting any time let's get started.....

// Hello friends welcome to "TECHNO-E-SOLUTION"
// Here is a code for control servomotor using Potentiometer


#include <Servo.h>

Servo myservo;

int potpin = 0;  // analog pin used to connect the potentiometer
int val;    // variable to read the value from the analog pin

void setup() {
  myservo.attach(11);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  val = analogRead(potpin);            
  val = map(val, 0, 1023, 0, 180);     
  myservo.write(val);                  
  delay(15);
