[Arduino] APDS-9960 手勢感測器

APDS-9960 是一顆手勢  + RGB感應器 ，我買的是


SparkFun RGB and Gesture Sensor - APDS-9960

手勢的部份支援

Left , Right , Up , Down , Near, Far

先把腳位焊上去，方便接線。

接下來去下載Lib的ZIP檔

https://github.com/sparkfun/SparkFun_APDS-9960_Sensor_Arduino_Library

加入ZIP程式庫

我是拿Gesture Test出來改的

接線方式


ADPS 9960        Arduino          

VCC                    3.3V

GND                  GND

SDA                   A4

SCL                  A5

INT                   2


LED

          上  4

          右  5

          下 6

          左 7

記得LED的GND 也要接到Arduino GND





程式碼 （拿範例程式來改，加上LED功能）

APDS-9960 RGB and Gesture Sensor

Tests the gesture sensing abilities of the APDS-9960. Configures
APDS-9960 over I2C and waits for gesture events. Calculates the
direction of the swipe (up, down, left, right) and displays it
on a serial console. 

To perform a NEAR gesture, hold your hand
far above the sensor and move it close to the sensor (within 2
inches). Hold your hand there for at least 1 second and move it
away.

To perform a FAR gesture, hold your hand within 2 inches of the
sensor for at least 1 second and then move it above (out of
range) of the sensor.

Hardware Connections:

IMPORTANT: The APDS-9960 can only accept 3.3V!
 
 Arduino Pin  APDS-9960 Board  Function
 
 3.3V         VCC              Power
 GND          GND              Ground
