Tests the proximity sensing abilities of the APDS-9930.
Configures the APDS-9930 over I2C and polls for the distance to
the object nearest the sensor.
Hardware Connections:
IMPORTANT: The APDS-9930 can only accept 3.3V!
Arduino Pin APDS-9930 Board Function
3.3V VCC Power
GND GND Ground
A4 SDA I2C Data
A5 SCL I2C Clock
Resources:
Include Wire.h and SparkFun_APDS-9930.h
Development environment specifics:
Written in Arduino 1.0.5
Tested with SparkFun Arduino Pro Mini 3.3V
This code is beerware; if you see me (or any other SparkFun
employee) at the local, and you've found our code helpful, please
buy us a round!
Distributed as-is; no warranty is given.
