Does a servo move to a position (i.e. position 45degrees) or move through an angle from where it initially starts? I use the command servo.write(45). But it just seems to continuously move. I would think that it would move to the 45 degree position and stop but this is not the case. Below, is the code:

/*
Arduino Servo Test sketch
*/
#include <Servo.h>
Servo servoMain; // Define our Servo

void setup()
{
servoMain.attach(9); // servo on digital pin 10
}

void loop()
{
servoMain.write(45); // Turn Servo Left to 45 degrees
delay(1000); // Wait 1 second

}

Is this different to your other thread? Are you certain it's not a 'continuous-rotation' servo? Does it stop if you set it to 90?

3

Ya it stops when set to 90.

Then it's a continuous-rotation servo. You need a proper servo.

Not to sound like a noob but whats the difference? Can you find me one off of sparkfun?

Here's one: Servo - Generic High Torque (Standard Size) - ROB-11965 - SparkFun Electronics. No idea of course whether it would suit your application, but it will at least behave as you expect.
