Controlling a servo position using a potentiometer (variable resistor) by Michal Rinott <http://people.interaction-ivrea.it/m.rinott>

#include <Servo.h>

Servo myservo; create servo object to control a servo 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(3); attaches the servo on pin 3 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, 179);     // 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
