The IRLib2 library has been incorporated into the Adafruit_CircuitPlayground library so if you've already installed that library you can skip to the next page which describes the tutorial programs. If you have not already installed library here is how to do it.
Installing Via Library Manager
The Circuit Playground library is available on the Adafruit GitHub website. The library is installed in versions of the Arduino IDE greater than 1.6.7 as follows:
Open up the Arduino library manager:
Search for Adafruit circuit playground library and install it. Make sure you put a space in-between circuit and playground as it will not show up otherwise.
Run the Demo
Plug in your Circuit Playground. Under Windows you'll need to make sure you have installed the driver package. Do that if you haven't!
Next, you'll also need to make sure you have installed the Adafruit Board Support package. That's required no matter what computer you're using.
Select the Circuit Playground Express Board
Under the Tools -> Board submenu, scroll down to Adafruit Boards and pick Adafruit Circuit Playground Express
Load the Demo Program
OK you're now ready to load the demo. Under File->Examples locate Adafruit CircuitPlayground and then select the demo program.
Compile/Verify the Demo
Click the Verify button (also the Sketch->Verify menu item) to compile/verify the demo. Make sure you get "Done compiling." and no errors
You should get a Done uploading. message in the blue statusbar
You can now run the serial console to get data output:
You'll get information such as:
- "Capacitive touch" readings for all 8 outer pads (under 50 means not touched, over 100 usually means the pads are touched)
- Slide switch location (left or right)
- If the Right and Left buttons are pressed
- Light sensor readings, higher values mean more light
- Sound sensor readings
- X, Y and Z accelerometer readings
- Temperature in Celcius
