This Arduino library implements a gesture recognizer for the Adafruit Circuit Playground that uses the built-in accelerometer, slide switch, and buttons to detect user gestures such as button presses, switch changes, shakes and taps, and more.
The accelerometer is used to detect
- double taps
- shakes
- orientation changes
The slide switch is used to detect
- switch turned on
- switch turned off
The two pushbuttons are used to detect
- either button clicked
- either button double-clicked
- either button held for a long press
- either button clicked while the other is held
- either button released
Client applications can use the gesture recognizer by calling its begin
method as part of their setup() function, and by calling its update method
frequently as part of the client's loop() function. The update method
returns an enumerated value indicating if any user gestures were detected
during that update cycle.
The GestureToSerial sketch in the examples directory demonstrates how an
application can use the library to detect user input gestures in the loop
function. The sketch prints a description of the received gestures to the serial
port.
