硬件连线
关键 VCC= 3.3v 不是 5v
下面这个库实测不起作用,不知道为什么
可用的库

/*
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.

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 ...");

1测试的时候刚上电不要对着强光,否则触发不了。
此函数来调整光触发值,0-100 默认80
应该是有一个光照强度值,跟初始上电瞬间采集到的光照有关系,基准值,发现触发不了的情况,断电,不要对着强光重启,复位不行。
2实际测试,其他物体也可以触发
还有2种其他手势可用:NEAR和FAR。
将手放在传感器上方(大于10英寸(25厘米)),使其靠近传感器(在传感器上方约2英寸(5厘米)),将其保持在至少1秒钟,然后移开您的手。
可以通过以下方式实现FAR手势:将手直接放在传感器上方并靠近传感器(大约2英寸(5厘米))至少1秒钟,然后将手直接向上移至传感器上方并超出传感器范围。
如果未正确解释手势,则“无”将出现在串行监视器中。
