Hello,

I am controlling a radio controlled car with arduino and processing. I am using an Logitech Dual action controller as an input device, and that device has an x/y values. I want to send one key with port.write when the x is 0 and another one when it is on max. No pwm controll on the car.

How can I do this? I am using procontroll library in processing. Right now I am sending data trough a cable, since my radio module died..

My code so far:

1. import processing.serial.*;
   import procontroll.*;
   
   ControllIO controllIO;
   ControllDevice joypad;
   
   Serial port;
   String portname = "COM3";
   int baudrate = 19200;
   
   
   
   void setup() {
      port = new Serial(this, portname, baudrate);
     controllIO = ControllIO.getInstance(this);
    
     joypad = controllIO.getDevice("Logitech Dual Action");
     joypad.plug(this, "forward", ControllIO.ON_PRESS, 8);
     joypad.plug(this, "stop_forward", ControllIO.ON_RELEASE, 8);
     joypad.plug(this, "backwards", ControllIO.ON_PRESS, 7);
     joypad.plug(this, "stop_backwards", ControllIO.ON_RELEASE, 7);
   }
    
     void forward() {
       port.write('w');
     }
    
     void stop_forward() {
       port.write('q');
     }
    
     void backwards() {
       port.write('s');
     }
    
     void stop_backwards() {
       port.write('e');
     }
    
   
   
   void draw() {
   }
