==Purpose==

This tutorial shows you the way to use servo under mCookie.   

==Equipment==
*'''[[Microduino-CoreUSB]]'''
*'''[[Microduino-Servo]]'''
*'''[[Microduino-Sensorhub]]'''


*Other Hardwar Equipment  
**USB cable   One 

==Program==

  #include <Servo.h> 
   
  Servo myservo;  // create servo object to control a servo 
                  // a maximum of eight servo objects can be created 
   
  int pos = 0;    // variable to store the servo position 
   
  void setup() 
  { 
    myservo.attach(9);  // attaches the servo on pin 9 to the servo object 
  } 
   
   
  void loop() 
  { 
    for(pos = 0; pos < 180; pos += 1)  // goes from 0 degrees to 180 degrees 
    {                                  // in steps of 1 degree 
      myservo.write(pos);              // tell servo to go to position in variable 'pos' 
      delay(15);                       // waits 15ms for the servo to reach the position 
    } 
    for(pos = 180; pos>=1; pos-=1)     // goes from 180 degrees to 0 degrees 
    {                                
      myservo.write(pos);              // tell servo to go to position in variable 'pos' 
      delay(15);                       // waits 15ms for the servo to reach the position 
    } 
  } 
==Debugging==

Step 1: 
Plug Microduino servo to D9 pin of Microduino-Sensorhub.

Step 2:
Connect USB cable to your PC, download the code and program it to Microduino-CoreUSB.

Step 3:   
After programming, the servo will swing among the reading of 0 to 180.

Step 4: 
Try to change the angle of swing repeatedly and see if it is accuracy.

==Result==

You can control the servo and make it swing to a certain angle.
