Overview
Controllers have a long history in our lives; from controlling remote control cars and quadcopters to game consols and …, they all use wireless or wired controllers. In this tutorial, you will learn how to connect and use a PS2 game console controller with Arduino.

PS2 Controllers Features
Everyone knows Sony game consoles called PlayStation, and you have probably held it at least once. Sony game controllers have 12 analog keys sensitive to pressure, (4 keys for direction, 4 operation keys, Cross, Triangle, Circle, and Square, L1, L2, R1, and R2) and 5 digital keys (MODE, START, SELECT, R3, L3) and 2 analog joysticks.
There are 2 motors inside controllers that can make vibration because of their imbalance.
The wireless controller works with 2, 4GHz frequency and it has a range of 10 meters. It also has an optical indicator for sending and receiving data. This controller needs only 3 AAA batteries for power (in some cases it needs just 2 AAA batteries).
Where you can use a PS2 controller:
- Controlling wheeled robots and remote control cars
- Controlling robotics arms
- Controlling a camera
- Controlling flying robots
- ..
How to Connect PS2 Controller to Arduino
PS2 controller receiver includes 9 pins:
- Data: master line for sending data to slave (MOSI)
- Command: slave line for sending data to master (MISO)
- Vibration: vibration motors supply; 7.2 volts to 9 volts
- Ground: circuits ground
- VCC: circuits supply; 3.3 volts
- Attention: CS or Chip Select pin for calling slave and preparing the connection
- Clock: equivalent to SCK pin for clock
- No Connection: useless
- Acknowledge: acknowledge signal from the controller to PS2 receiver
Interfacing PS2 Controller and Arduino
In order to use a PS2 controller, you need to introduce the controllers key to Arduino. Then choose a proper function for each key according to your project.
Circuit
Code
You need to use the PS2X library for this code.
After adding the library to Arduino, you can open PS2X library Example or Copy the following code and upload it on your board. You can see the results in the serial monitor window by pressing different keys.
#include #include <PS2X_lib.h> PS2X ps2x; //right now, the library does NOT support hot-pluggable controllers, meaning //you must always either restart your Arduino after you connect the controller, //or call config_gamepad(pins) again after connecting the controller. int error = 0; byte type = 0; byte vibrate = 0; void setup(){ Serial.begin(57600); error = ps2x.config_gamepad(13,11,10,12, true, true); //GamePad(clock, command, attention, data, Pressures?, Rumble?) 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 www.billporter.info for updates and to report bugs."); } else if(error == 1) Serial.println("No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips"); else if(error == 2) Serial.println("Controller found but not accepting commands. see readme.txt to enable debug. Visit www.billporter.info for troubleshooting tips"); else if(error == 3) Serial.println("Controller refusing to enter Pressures mode, may not support it. "); type = ps2x.readType(); switch(type) { case 0: Serial.println("Unknown Controller type"); break; case 1: Serial.println("DualShock Controller Found"); break; case 2: Serial.println("GuitarHero Controller Found"); break; } } 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) return; if(type == 2){ ps2x.read_gamepad(); //read controller if(ps2x.ButtonPressed(GREEN_FRET)) Serial.println("Green Fret Pressed"); if(ps2x.ButtonPressed(RED_FRET)) Serial.println("Red Fret Pressed"); if(ps2x.ButtonPressed(YELLOW_FRET)) Serial.println("Yellow Fret Pressed"); if(ps2x.ButtonPressed(BLUE_FRET)) Serial.println("Blue Fret Pressed"); if(ps2x.ButtonPressed(ORANGE_FRET)) Serial.println("Orange Fret Pressed"); if(ps2x.ButtonPressed(STAR_POWER)) Serial.println("Star Power Command"); if(ps2x.Button(UP_STRUM)) //will be TRUE as long as button is pressed Serial.println("Up Strum"); if(ps2x.Button(DOWN_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"); if(ps2x.Button(PSB_SELECT)) 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"); if(ps2x.Button(PSB_SELECT)) 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); } if(ps2x.Button(PSB_PAD_RIGHT)){ Serial.print("Right held this hard: "); Serial.println(ps2x.Analog(PSAB_PAD_RIGHT), DEC); } if(ps2x.Button(PSB_PAD_LEFT)){ Serial.print("LEFT held this hard: "); Serial.println(ps2x.Analog(PSAB_PAD_LEFT), DEC); } if(ps2x.Button(PSB_PAD_DOWN)){ 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) { if(ps2x.Button(PSB_L3)) Serial.println("L3 pressed"); if(ps2x.Button(PSB_R3)) Serial.println("R3 pressed"); if(ps2x.Button(PSB_L2)) Serial.println("L2 pressed"); if(ps2x.Button(PSB_R2)) Serial.println("R2 pressed"); if(ps2x.Button(PSB_GREEN)) 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(","); Serial.print(ps2x.Analog(PSS_LX), DEC); Serial.print(","); Serial.print(ps2x.Analog(PSS_RY), DEC); Serial.print(","); Serial.println(ps2x.Analog(PSS_RX), DEC); } } delay(50); } The most practical functions in this library are:
ps2x.config_gamepad(clock, command, attention, data, Pressures? Rumble?); function sets the controller pin and sensitivity to pressure and vibration of the motors. If you want keys insensitive to pressure, or motors don't have vibration, set Pressures, and Rumble as false. This function returns value for error
ready(); function determine the detected controller type. 0 means the controller is not detected correctly, 1 means DualShock controller detection, and 2 means GuitarHero controller detection.
read_gamepad(boolean motor1, byte motor2); function start reading the status of the keys when the state of the vibration of the motor is determined. (motor 2 is the bigger one.)
Button (but type); function returns 1 when the specific key in function argument is pressed. In DualShock controller keys are named as follows:
Analog (but type); function returns analog keys value, then you can decide for your operation accordingly.
What's Next?
- Try to build a remote control car with 2 wheels that moves to a different direction by pressing direction keys. And the cars speed change with the amount of pressure on the key. The car beeps by pressing a square key, and its lights turn on with pressing the cross key.
