  Hello everyone,
  I'm trying to work with the accelerometer/gyroscope in the puck.js v2.

  I wrote a small script to transmitt accelerometer data over bluetooth as follows:

  var running = false;
  
  function accelHandlerTrigger(data) {
    console.log(data);
    var d = [
      "A",
      Math.round(data.acc.x),
      Math.round(data.acc.y),
      Math.round(data.acc.z)
    ];
    Bluetooth.println(d.join(","));
  }
  
  setWatch(function() {
    if (running) {
      Puck.accelOff();
      Puck.removeListener('accel', accelHandlerTrigger);
      running = false;
    } else {
      running = true;
      Puck.accelOn(52);
      Puck.on('accel', accelHandlerTrigger);
    }
  }, BTN, {repeat:true});
  

  However, the sensor measurements that I get seems to be too high. For example:

  "acc": { "x": -342, "y": 398, "z": 8270 }, 
  "gyro": { "x": 313, "y": -299, "z": -92 }
  
  "acc": { "x": -319, "y": 371, "z": 8098 }, 
  "gyro": { "x": 167, "y": -290, "z": -69 }
  

  From my understanding, the accelerometer default is ±2g and the gyroscope default is ±125 dps.

  Is this correct? or why are the values too high?
