// 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(9); // attaches the servo on pin 9 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 | |
