A colorful CLUE slideshow purse with Bright Wearables

Libraries

Once your CLUE is set up with CircuitPython and library files in general, we'll add some project specific libraries.

From the library bundle you downloaded in that guide page, transfer any additional libraries shown here onto the CLUE's /lib directory on the CIRCUITPY drive:

adafruit_apds9960
adafruit_bus_device
adafruit_bmp280
adafruit_clue.py
adafruit_dotstar.mpy
adafruit_fancyled
adafruit_imageload
adafruit_lis3mdl.mpy
adafruit_lsm6ds.mpy
adafruit_register
adafruit_sht31d.mpy
adafruit_slideshow.mpy
neopixel.mpy

Text Editor

Adafruit recommends using the Mu editor for using your CircuitPython code with the CLUE boards. You can get more info in this guide.

Alternatively, you can use any text editor that saves files.

Plug your CLUE into your computer via a known good USB cable. In your operating system's file explorer/finder, you should see a new flash drive named CIRCUITPY. Copy the code.py file and the three sample bmp files to the CLUE CIRCUITPY drive main (root) folder.

The files on your CLUE should be similar to the directory tree listed on this page. The first three files may not show up on a mac, they tell OSX to not put system files on the CLUE CIRCUITPY drive which might fill it up.
