APDS9930 Ambient Light and Proximity sensor
===========================================
This is a fork of the [library from Sparkfun for the APDS-9960 sensor](https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor). It has been adapted to read values from this other model.
[**Quick-start guide available here**](https://web.archive.org/web/20151224052223/http://davideddu.org/blog/posts/apds-9930-arduino-quickstart/)
[**Purchase an Avago APDS-9930 Breakout Board here**](http://www.dx.com/p/384037?Utm_rid=14976370&Utm_source=affiliate)
# DO NOT EMAIL ME IF YOU HAVE AN ISSUE
It will be deleted without reading. If you have an issue, [create an issue](https://github.com/Depau/APDS9930/issues) here on GitHub.
# Unmaintained
I'm not going to maintain this library any more. I will merge pull requests, though. Contributions are welcome. Just don't expect anything from me.
![Avago APDS-9930 Breakout Board](http://img.dxcdn.com/productimages/sku_384037_1.jpg)
**Note:** even though it says APDS-9960, it's an APDS-9930. That's how I ended up getting one of those. I wanted the RGB sensor. I found this crap in my mailbox. But I decided to write a library for it anyways ;)
Getting Started
---------------
* Download the Git repository as a ZIP ("Download ZIP" button)
* Unzip
* Copy the entire library directory (APDS-9930) to
\<Arduino installation directory\>/libraries
* Open the Arduino program
* Select File -> Examples -> APDS9930 -> GestureTest
* Plug in your Arduino and APDS-9930 with the following connections
*-OR-*
* Use the library manager
| Arduino Pin | APDS-9930 Board | Function |
|---|---|---|
| 3.3V | VCC | Power |
| GND | GND | Ground |
| A4 | SDA | I²C Data |
| A5 | SCL | I²C Clock |
| 2 | INT | Interrupt |
*P.S.: you already know you can't use this purple little thing with your 5V Arduino without a level shifter, right? :) In case you don't have a level shifter, you can detach the microcontroller from an Arduino Uno, reconnect the oscillator pins, the RX and TX pins, the reset and the LED/SCK pins back to the board with some jumper wires. You can then power the microcontroller from a 3.3V source (the 3V3 output on the board should work) and connect the sensor directly to the MCU. Look up "Arduino on Breadboard".*
* Go to Tools -> Board and select your Arduino board
* Go to Tools -> Serial Port and select the COM port of your Arduino board
* Click "Upload"
* Go to Tools -> Serial Monitor
* Ensure the baud rate is set at 9600 baud
* Swipe your hand over the sensor in various directions!
Repository Contents
-------------------
* **/examples** - Example sketches for the library (.ino). Run these from the Arduino IDE.
* **/extras** - Additional documentation for the user. These files are ignored by the IDE.
* **/src** - Source files for the library (.cpp, .h).
* **keywords.txt** - Keywords from this library that will be highlighted in the Arduino IDE.
* **library.properties** - General library properties for the Arduino package manager.
Documentation
--------------
* **[Quickstart Guide](https://web.archive.org/web/20151224052223/http://davideddu.org/blog/posts/apds-9930-arduino-quickstart/)** - Basic hookup guide for the sensor.
* **[Product Repository](https://github.com/Davideddu/APDS9930)** - Main repository (including hardware files) for the APDS9930 ambient light and proximity sensor.
* **[Installing an Arduino Library Guide](https://learn.sparkfun.com/tutorials/installing-an-arduino-library)** - Basic information on how to install an Arduino library.
Version History
---------------
* master - Adapted for use with APDS-9930
* [V_1.4.0](https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor_Arduino_Library/tree/V_1.4.0) - Updated to new library structure
* V_1.3.0 - Implemented disableProximitySensor(). Thanks to jmg5150 for catching that!
* V_1.2.0 - Added pinMode line to GestureTest demo to fix interrupt bug with some Arduinos
* V_1.1.0 - Updated GestureTest demo to not freeze with fast swipes
* V_1.0.0: Initial release
* Ambient and RGB light sensing implemented
* Ambient light interrupts working
* Proximity sensing implemented
* Proximity interrupts working

AmbientLightInterrupt.ino
APDS-9930 RGB and Gesture Sensor
Shawn Hymel @ SparkFun Electronics
October 24, 2014
https://github.com/sparkfun/APDS-9930_RGB_and_Gesture_Sensor
Tests the ambient light interrupt abilities of the APDS-9930.
Configures the APDS-9930 over I2C and waits for an external
interrupt based on high or low light conditions. Try covering
the sensor with your hand or bringing the sensor close to a
bright light source. You might need to adjust the LIGHT_INT_HIGH
and LIGHT_INT_LOW values to get the interrupt to work correctly.
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
2 INT Interrupt
13 - LED
Resources:
Include Wire.h and APDS9930.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!

Tests the proximity interrupt abilities of the APDS-9930.
Configures the APDS-9930 over I2C and waits for an external
interrupt based on high or low proximity conditions. Move your
hand near the sensor and watch the LED on pin 13.
