Hi.

I am trying to do something that I though would be quite simple but it has quickly confused me. I have an IMU connected to an Arduino and it is sending Roll, Pitch and Yaw values to Processing over the serial port. I am trying to map these values to the RotateX,Y & Z values of a cube. The values are printing in processing but when I try to map these to the cubes rotation strange things happen, the cube flashes and bounces all over the screen. The code that I am using is below, any help would be greatly appreciated, Thanks!!
PS. this is what prints in the terminal, values range from -180 to +180 :
Sensor 0: 0.92    Roll
Sensor 1: 2.36    Pitch
Sensor 2: -51.58    Yaw

   import processing.serial.*;     // import the Processing serial library
   Serial myPort;                  // The serial port
   
   float bgcolor;            // Background color
   float fgcolor;            // Fill color
   float xpos, ypos;            // Starting position of the ball
   
   void setup() {
     frameRate(30);
     size(640,480, P3D);
     background(0);
     lights();
     // List all the available serial ports
     println(Serial.list());
     myPort = new Serial(this, Serial.list()[1], 9600);
   
     // read bytes into a buffer until you get a linefeed (ASCII 10):
     myPort.bufferUntil('\n');
    
     // draw with smooth edges:
     smooth();
   }
   
   void draw() {
   }
   
   void serialEvent(Serial myPort) {
     background(0);
     noStroke();
     pushMatrix();
     translate(width/2, height/2);
    
     // read the serial buffer:
     String myString = myPort.readStringUntil('\n');
     // if you got any bytes other than the linefeed:
       myString = trim(myString);
    
       // split the string at the commas
       // and convert the sections into integers:
       float sensors[] = float(split(myString, ','));
   //println("roll: " + sensors[0] + " pitch: " + sensors[1] + " yaw: " + sensors[2] + "\t");
       // print out the values you got:
       for (int sensorNum = 0; sensorNum < sensors.length; sensorNum++) {
         print("Sensor " + sensorNum + ": " + sensors[sensorNum] + "\t");
        if (sensorNum == 0) {
          println("Roll");
          //rotateX(sensors[0]);
   
        }
        if (sensorNum == 1) {
          println("Pitch");
          //rotateY(sensors[1]);
   
        }
        if (sensorNum == 2) {
          println("Yaw");
          //rotateZ(sensors[2]);
        }
       
       }
       // add a linefeed after all the sensor values are printed:
       println();
       box(100);
       popMatrix();
       if (sensors.length > 1) {
         rotateX(sensors[0]);
         rotateY(sensors[1]);
         rotateZ(sensors[2]);
       }
       // send a byte to ask for more data:
       myPort.write("A");
     }
    

I am working on a projects that requires two arduinos to be connected to a processing sketch (one local & one wireless)
I have started by assessing whether this is possible or not by using the code below to turn an led on on each board.  The codes compiles without any errors nor do I get any errors at runtime, however, it just will not communicate with the two boards.  Has anyone attempted this before or would you have any advise for me..

Big Thanks,
