Using a potentiometer to turn a servo via an arduino uno, and some code.
Here is the video http://www.youtube.com/watch?v=3MyjufWWzFQ
#include <Servo.h>
Servo myservo; // create servo object to control a servo
int sensorPin = A0; // select the input pin for the potentiometer
int servoPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor
int val;
void setup() {
Serial.begin(9600);
myservo.attach(servoPin);
}
void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
Serial.println(sensorValue);
val = map(sensorValue, 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);
}
