|
|
|
|
Tests the proximity sensing abilities of the APDS-9960.
|
|
Configures the APDS-9960 over I2C and polls for the distance to
|
|
the object nearest 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
|
|
A4 SDA I2C Data
|
|
A5 SCL I2C Clock
|
|
|
|
Resources:
|
|
Include Wire.h and SparkFun_APDS-9960.h
|
|
|
|
Development environment specifics:
|
|
Written in Arduino 1.0.5
|
|
Tested with SparkFun Arduino Pro Mini 3.3V
|
|
|
|
