Install CircuitPython
The first think to do is install CircuitPython on your Funhouse. Follow this guide to get it set up with the latest release version.
Shhhh... Secrets
In order for the Funhouse to connect to the internet, you'll need to include a secrets.py file on the board that contains your WiFi access point ssid and password, as well as your AIO key.
Follow this guide page to get your secrets.py file set up.
Add LIFX Token to secrets.py
Add your LIFX token to the secrets.py file on it's own line. It should look something like this:
# This file is where you keep secret settings, passwords, and tokens!
# If you put them in the code you risk committing that info or sharing it
secrets = {
'ssid' : 'your_access_point',
'password' : 'your_wifi_password',
'lifx_token' : 'YOUR_APP_TOKEN'
}
Text Editor
Adafruit recommends using the Mu editor for using your CircuitPython code with the Funhouse. You can get more info in this guide.
Download the Project Bundle
Your project will use a specific set of CircuitPython libraries and the code.py file. In order to get the libraries you need, click on the Download Project Bundle link below, and uncompress the .zip file.
Next, drag the contents of the uncompressed bundle directory onto you microcontroller board CIRCUITPY drive, replacing any existing files or directories with the same names, and adding any new ones that are necessary.
