readGesture()

Açıklama

Sensörden algılanan hareketi okuyun. APDS.gestureAvailable() işlevini kullanarak bir hareketin algılanıp algılanmadığını kontrol edebilirsiniz.

Sözdizimi

APDS.readGesture ()

Parametreler

Yok

İadeler

Algılanan hareket.
Aşağıdaki değerlerden biri olabilir:

GESTURE_UP - "yukarı" hareket
GESTURE_DOWN - "aşağı" hareketi
GESTURE_LEFT - "sol" hareket
GESTURE_RIGHT - "doğru" jest
GESTURE_NONE - hareket yukarıdakilerin hiçbiriyle eşleşmiyor

Misal

/*
APDS9960 - Gesture Sensor

This example reads gesture data from the on-board APDS9960 sensor of the
Nano 33 BLE Sense and prints any detected gestures to the Serial Monitor.

Gesture directions are as follows:
- UP: from USB connector towards antenna
- DOWN: from antenna towards USB connector
- LEFT: from analog pins side towards digital pins side
- RIGHT: from digital pins side towards analog pins side

The circuit:
- Arduino Nano 33 BLE Sense

This example code is in the public domain.

void setup() {
Serial.begin(9600);
while (!Serial);

if (!APDS.begin()) {
Serial.println("Error initializing APDS9960 sensor!");
}

// for setGestureSensitivity(..) a value between 1 and 100 is required.
// Higher values makes the gesture recognition more sensible but less accurate
// (a wrong gesture may be detected). Lower values makes the gesture recognition
// more accurate but less sensible (some gestures may be missed).
// Default is 80
//APDS.setGestureSensitivity(80);

Serial.println("Detecting gestures ...");

void loop() {
if (APDS.gestureAvailable()) {
// a gesture was detected, read and print to serial monitor
