accelerometer

The accelerometer is an object representing the accelerometer sensor attached to the Circuit Playground.

Properties and Methods

• accelerometer.getOrientation() - Get the orientation of the board (i.e tilting forward, back, side to side, spinning, etc)
• accelerometer.getAcceleration()-

Events

The accelerometer has a fair amount of event types as well.

Event	Description
Change	Fired any time the accelerometer experiences a change
Data	Fires every 50 milliseconds
Single Tap	Fires only when a tap is detected next to the board.
Double Tap	Fires only when two taps within x amount of time of each other is detected next to the board.

Examples

Tilt Detector

Lights up the color LEDs based on how the board is being tilted.

var colors = "white";

onBoardEvent(accelerometer, "data", function(event) {
  var pitch = accelerometer.getOrientation("pitch");
  var inclination = accelerometer.getOrientation("inclination");
  var roll = accelerometer.getOrientation("roll");
  
  //front to back
  if (pitch < -10) {
    colorLeds[0].on();
    colorLeds[9].on();
  }
  if (pitch > 10) {
    colorLeds[4].on();
    colorLeds[5].on();
  }
  
  //side-to-side
  if (roll > 20) {
    colorLeds[7].on();
  } 
  if(roll < -20){
    colorLeds[2].on();
  }
});
