Controlling servo motor using potentiometer

• Arduino uno

• B50k potentiometer

• Servo motor

• Jumper wire

• Servo red wire to to 5v

• Servo brown wire to Gnd

• Servo orange wire to digital pin 9

• left pin of potentiometer to 5 v

• middle pin of potetiometer to Analog pin one

• right pin of potentiometer to Gnd

#include <Servo.h> //accesses the Arduino Servo Library

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

int val; // variable to read the value from the analog pin

void setup()

{

myservo.attach(9); // ensures output to servo on pin 9

}

void loop()

{

val = analogRead(1); // reads the value of the potentiometer from A1 (value between 0 and 1023)

val = map(val, 0, 1023, 0, 180); // converts reading from potentiometer to an output value in degrees of rotation that the servo can understand

myservo.write(val); // sets the servo position according to the input from the potentiometer

delay(15); // waits 15ms for the servo to get to set position
