Interfacing Wireless PS2 Controller with Arduino
Hi, in this tutorial we’ll try to interface a PS2 wireless controller with Arduino UNO board, it is very interesting since all the controller’s buttons would be inputs for the Arduino board and not only that but also wireless, using 2.4GHz Radio Frequency communication protocol, which can be very useful to control robots, vehicles, servos…
I bought this controller with A servo dedicated board for 30 USD, you can get the controller/Receiver much cheaper, but don’t forget that these cheap devices have some problems (you can see it in the video), the sensitivity is not that good comparing it with the original controller, also you may experience some push button problems…
You can learn a lot about this controller visiting this website:Â billporter.info
Wiring:
Considering from which side you are observing this is the order I followed, the pins #3 and #8 don’t have a connector at all, also we’re not using the pin #9.
Wiring with the usual LCD i2c screen, I used with the code I made.
Libraries:
Here you can download the libraries required for the devices, The LCD i2c library is optional and only used if you are using one:
- Download PS2X Library. Don’t forget that the directory named “PS2X_lib” must be present in the libraries directory
- Download LCD i2c Library
Codes:
You can download the code using LCD here, or check below
Code 1: Example from the library
The first code you’ll find it in the library, it shows different functions you can use such as reading the analog stick values, detect if a button is pressed, released or being held…., also it detects which type of controller you are using or showing you an error if there is one.

Code 2: Test with LCD i2c screen
The second code just takes few functions and shows the value or the buttons that are being pressed on the screen, here I only associated printing on lcd screen for every function, but for you, you can control servos, dc motors, LEDs… overall it’s just an example for the tutorial.

Automation and Electrical Engineer, Electronics amateur trying to share my little projects.
How can I deactivate the vibration of the control, to perform a test without the possibility of damaging the PC input?
good contribution!!
Remove the line vibrate = ps2x.Analog(PSAB_BLUE) or comment it
brother, I want to do a counter using some axis of the stick to control servos later,
the problem is that I want to use the value (controlps.Analog (PSS_LY), DEC); and use conditional “if” to increase or decrease said counter.
when doing this, the “++ or –” operation does not respond, but the function does recognize the real-time position of the stick,
can you support me to determine the fault ?.
—————————————————————–
#include //
PS2X controlps; // create PS2 Controller Class
int contadorservo;//—–>counter variable
void setup() {
controlps.config_gamepad(13,11,10,12, false, false); // GamePad(clock, command, attention, data, Pressures?, Rumble?) check for error
Serial.begin(9600);
}
void loop() {
byte vibrate = 0;
int lectura=(controlps.Analog(PSS_LY), DEC);
controlps.read_gamepad(false, vibrate);
if(lectura==0) {contadorservo=contadorservo++;} //condicional only for fast test
if(lectura==128){contadorservo=contadorservo;}
if(lectura==255){contadorservo=contadorservo–;}
Serial.print(contadorservo); //—–> print the data
Serial.print(” “);
Serial.println(controlps.Analog(PSS_LY), DEC);
}

Best regards and grace for the support
Hi I’ll take a look to this, do you want to control a servo using the stick? because I have done a project where I control dual axis camera tilt with a ps2x stick.
Try this writing
if(lectura==0)
contadorservo++;
if(lectura==255)
contadorservo–-;
Try not to copy/paste this directly it may result in some errors like “stray ‘\342’ in program” and it won’t compile.
brother could you make a post with the code with the project that you tell me, I would like to have a reference with a functional project, the example of arduino has several functions running and on the internet I only find projects using buttons and no stick
thank you for your support my email is marckoe93@hotmail.com

You can check this project: https://surtrtech.com/2019/01/17/arduino-rc-laser-tank-self-propelled-laser-turret/
And here I have just a thumbstick (not the wireless joystick) with 2 servos using 2 different manners to control: https://surtrtech.com/2018/01/30/control-dual-axis-fpv-camera-cradle-with-joystick-module/

Controller found but not accepting commands
DualShock Controller Found
how to fix that?
its connected but when i click any button there is no command
can you give the exact wiring you used in the video because all the schematics dont match
Hello, you can check the wiring and read its description carefully, also be aware of the modules direction (round or pointy edge top or bottom).
