The Arduino101Button component lets users listen to events triggered by a button connected to a digital pin on the Arduino. The extension responds to voltage changes on the specified digital Pin
and so can be used to respond to any hardware component that signals high/low based on some external phenomenon, such as a motion detector.

BluetoothDevice
– The BluetoothLE component with a connection to the Arduino 101.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.ReadButtonState
– Read the current state of the button as reported by the Arduino. On success, the
ButtonStateReceived
event will be run. If the
state of the button has changed, the Pressed
or
Released
events will be run as well.RequestButtonStateUpdates
– Request notifications from the Arduino for changes in the button state. The ButtonStateReceived
event will be run after
every sample is received, even if no change occurs. If a change in the state occurs, either
the Pressed
or the Released
event will be run.StopButtonStateUpdates
– Stop listening for notifications of button states from the Arduino. This only has an effect
if there was a previous call to RequestButtonStateUpdates
. There may be
additional pending messages that will be processed after this call, so if accuracy in the
data delivery are important an additional variable should be used to track the state of
event processing.ButtonStateReceived
– The ButtonStateReceived
event is run when any button state is received by the
Bluetooth low energy component from the Arduino. This state value may be the same for
extended periods of time if the button switch is left in an open or closed state.
Parameter:
Button_State
(number) — The button state: 0 if released, 1 if pressed.
