#### Sample Program: Gestures

The Futureboard can detect 8 gestures:

1. ‘shake’
2. ‘freefall’
3. ‘tilt\_up’
4. ‘tilt\_down’
5. ‘tilt\_left’
6. ‘tilt\_right’
7. ‘face\_up’
8. ‘face\_down’

Shake the FutureBoard for a sound.

#### Sample Program: Gesture Triggers

Shake the FutureBoard for a sound.

```
Note: Trigger Events only work when the program is uploaded onto the FutureBoard.
```

#### Sample Program: Magnetic Sensor

The magnetic sensor has a range of ±800(μT)。

The magnetic strengths are shown on FutureBoard.

```
The magnetic sensor needs to be calibrated before use.

#### Sample Program: Compass

The compass returns a compass bearing, with 0 indicating North.

The compass bearing is shown.
