PS2 controller connect to arudino uno in order to control servo

Hi everyone,

I am trying to use PS2 controller to control servos, but I face some problems.

I use a library which download from the website . But the value from arduino is not quit accurately. For example, serial monitor shows the signal twenty minutes after I press the button such as triangle one or squire one. But when I press START button, serial monitor shows signal immediately.

I don’t know how to solve this problem, please someone tell me.

The second problem is I don’t know how to use PS2 controller to control servo.
The following is the code I write:

#include <PS2X_lib.h>  //for v1.6
#include <Servo.h>

PS2X ps2x; // create PS2 Controller Class

Servo myservo;

//right now, the library does NOT support hot pluggable controllers, meaning 
//you must always either restart your Arduino after you conect the controller, 
//or call config_gamepad(pins) again after connecting the controller.
int error = 0; 
byte type = 0;
byte vibrate = 0;

void setup(){

 //CHANGES for v1.6 HERE!!! **************PAY ATTENTION*************
 error = ps2x.config_gamepad(13,11,10,12, true, true);   //setup pins and settings:  GamePad(clock, command, attention, data, Pressures?, Rumble?) check for error
 if(error == 0){
   Serial.println("Found Controller, configured successful");
   Serial.println("Try out all the buttons, X will vibrate the controller, faster as you press harder;");
  Serial.println("holding L1 or R1 will print out the analog stick values.");
  Serial.println("Go to for updates and to report bugs.");
  else if(error == 1)
   Serial.println("No controller found, check wiring, see readme.txt to enable debug. visit for troubleshooting tips");
  else if(error == 2)
   Serial.println("Controller found but not accepting commands. see readme.txt to enable debug. Visit for troubleshooting tips");
  else if(error == 3)
   Serial.println("Controller refusing to enter Pressures mode, may not support it. ");
   //Serial.print(ps2x.Analog(1), HEX);
   type = ps2x.readType(); 
     switch(type) {
       case 0:
        Serial.println("Unknown Controller type");
       case 1:
        Serial.println("DualShock Controller Found");
       case 2:
         Serial.println("GuitarHero Controller Found");

void loop(){
   /* You must Read Gamepad to get new values
   Read GamePad and set vibration values
   ps2x.read_gamepad(small motor on/off, larger motor strenght from 0-255)
   if you don't enable the rumble, use ps2x.read_gamepad(); with no values
   you should call this at least once a second
 if(error == 1) //skip loop if no controller found
 if(type == 2){ //Guitar Hero Controller
   ps2x.read_gamepad();          //read controller 
     Serial.println("Green Fret Pressed");
     Serial.println("Red Fret Pressed");
     Serial.println("Yellow Fret Pressed");
     Serial.println("Blue Fret Pressed");
     Serial.println("Orange Fret Pressed");

     Serial.println("Star Power Command");
    if(ps2x.Button(UP_STRUM))          //will be TRUE as long as button is pressed
     Serial.println("Up Strum");
     Serial.println("DOWN Strum");
    if(ps2x.Button(PSB_START))                   //will be TRUE as long as button is pressed
         Serial.println("Start is being held");
         Serial.println("Select is being held");

    if(ps2x.Button(ORANGE_FRET)) // print stick value IF TRUE
        Serial.print("Wammy Bar Position:");
        Serial.println(ps2x.Analog(WHAMMY_BAR), DEC); 

 else { //DualShock Controller
    ps2x.read_gamepad(false, vibrate);          //read controller and set large motor to spin at 'vibrate' speed
    if(ps2x.Button(PSB_START))                   //will be TRUE as long as button is pressed
         Serial.println("Start is being held");
         Serial.println("Select is being held");
     if(ps2x.Button(PSB_PAD_UP)) {         //will be TRUE as long as button is pressed
       Serial.print("Up held this hard: ");
       Serial.println(ps2x.Analog(PSAB_PAD_UP), DEC);
       Serial.print("Right held this hard: ");
        Serial.println(ps2x.Analog(PSAB_PAD_RIGHT), DEC);
       Serial.print("LEFT held this hard: ");
        Serial.println(ps2x.Analog(PSAB_PAD_LEFT), DEC);
       Serial.print("DOWN held this hard: ");
     Serial.println(ps2x.Analog(PSAB_PAD_DOWN), DEC);
      vibrate = ps2x.Analog(PSAB_BLUE);        //this will set the large motor vibrate speed based on 
                                              //how hard you press the blue (X) button    
    if (ps2x.NewButtonState())               //will be TRUE if any button changes state (on to off, or off to on)
         Serial.println("L3 pressed");
         Serial.println("R3 pressed");
         Serial.println("L2 pressed");
         Serial.println("R2 pressed");
         Serial.println("Triangle pressed");
    if(ps2x.ButtonPressed(PSB_RED))             //will be TRUE if button was JUST pressed
         Serial.println("Circle just pressed");
    if(ps2x.ButtonReleased(PSB_PINK))             //will be TRUE if button was JUST released
         Serial.println("Square just released");     
    if(ps2x.NewButtonState(PSB_BLUE))            //will be TRUE if button was JUST pressed OR released
         Serial.println("X just changed");    
    if(ps2x.Button(PSB_L1) || ps2x.Button(PSB_R1)) // print stick values if either is TRUE
        Serial.print("Stick Values:");
        Serial.print(ps2x.Analog(PSS_LY), DEC); //Left stick, Y axis. Other options: LX, RY, RX  
        Serial.print(ps2x.Analog(PSS_LX), DEC); 
        Serial.print(ps2x.Analog(PSS_RY), DEC); 
        Serial.println(ps2x.Analog(PSS_RX), DEC); 

I verify it on arduino IDE and it finish successfully. But when I upload to arduino uno board, it can’t run as I expect. Arduino can read the value which come from PS2 controller and can show value on serial monitor.

Please someone help me to solve this problem. THANK YOU!!!
