属性

• BluetoothDevice – The BluetoothLE component with a connection to the Arduino 101.

• Pin – The Pin on the Arduino board that the device is wired in to.

方法

• IsSupported – Tests whether the Bluetooth low energy device is broadcasting support for the service. If true, calls to TurnOn and TurnOff should work correctly. Otherwise an error will be reported through the Screen’s ErrorOccurred event.

• SetPosition – Set the rotation of a positional servo. Valid values are 0-180 degrees.

Parameters:

 * <code>position</code> (<a href="http://appinventor.mit.edu/explore/ai2/support/blocks/math.html#number">_number_</a>) &mdash;
   The new position of the servo in degrees. Valid values are 0-180.

• SetPositionMicros – Set the time per revolution in microseconds of a continuous rotation servo. For a standard servo, 1000 is fully counterclockwise and 2000 is fully clockwise.

Parameters:

 * <code>position</code> (<a href="http://appinventor.mit.edu/explore/ai2/support/blocks/math.html#number">_number_</a>) &mdash;
   The new rotational speed for a continuous rotational servo.

事件

• PositionWritten – The PositionWritten event is run after a successful write to the servo’s position. The meaning of the position parameter depends on whether position update was triggered by a SetPosition call or a SetPositionMicros call.

Parameters:

 * <code>position</code> (<a href="http://appinventor.mit.edu/explore/ai2/support/blocks/math.html#number">_number_</a>) &mdash;
   The new position of the servo. If the call was positional, this will be in degrees. If the call was rotational, it will be in microseconds.
