I received my kits today, Finally I can start with my first module of Enchanted Wardrobe. It would be around the Yun.

P.S the servo is quiet big, I got an idea to use it wisely ,@STAY TUNED! for more.

Thanks Element14 once again...

Here's the review and a test bed: Review 3: Digital Continuous Rotation (360°) Servo . My next challenge is to find a nifty way to use this type of motor. I wasn't expecting a continuous servo. It's surprises…

The servo has got a bit of power to it, in my test yesterday it seemed to rotate about 380° when I ran the 0 to 180° sweep code into it.

LOL that is a lot of omph in that motor. Maybe you need to slow it down a bit.

Could be a timing issue? You can try the Arduino - ServoWriteMicroseconds command based on the values in the datasheet if mentioned, see if that helps.

I suspect that attaching it with a min and max would work.

servo.attach(pin, min, max)

It's indeed a 360° motor. I've tested it, and it's capable of doing a little more than full circle, just like you experienced.
The motor has a model number SM-S4303R on it. Datasheets tell that this is a 'Continuous Rotation Servo'.
These continuous motors are a bit tricky to program and calibrate.
Here's a slow runner I just bodged together:
```
#include <Servo.h> 

Servo myservo;  // create servo object to control a servo 
                // twelve servo objects can be created on most boards

int pos = 90;    // variable to store the servo position 

void setup() 
{ 
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 
  myservo.write(90);
} 

void loop() 
{ 
  myservo.write(100);
  delay(15);
}
```

I'm still learning about this, but these servos work differently.

If you write 90 to them, they stop, in the current position, not in a fixed 0 point.
A value lower than 90: turn left. The lower the value, the faster the speed.
A value higher than 90: turn right The higer the value, the faster the speed.
