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.

• ReadMoisture – Obtain the most recent reading from the moisture sensor as reported by the Arduino. On success, the MoistureReceived event will be run.

• RequestMoistureUpdates – Request notification of updates for the moisture sensor attached to the Arduino 101. The MoistureReceived event will be run as moisture sensor readings are received from the Arduino.

• StopMoistureUpdates – Stop listening for notifications of moisture sensor readings from the ARduino. This only has an effect if there was a previous call to RequestMoistureUpdates. There may be additional pending messages that will be processed after this call.

事件

• MoistureReceived – The MoistureReceived event is run when a moisture measurement is received from the moisture sensor attached to the Arduino 101.

Parameters:

 * <code>moisture</code> (<a href="http://appinventor.mit.edu/explore/ai2/support/blocks/math.html#number">_number_</a>) &mdash; The moisture level measured, between 0 and 100.
