Install the Monster Eyes Library
Text emphasized with a blue info:
Monster Eyes is an Arduino sketch. CircuitPython is installed to use the CIRCUITPY file system to store eyeball graphics.
You can install the Adafruit Monster Eyes library through the Arduino IDE and then load the included examples to get started with all things animated eyeballs.
Click the Manage Libraries ... menu item, search for Adafruit Monster Eyes, and select the Adafruit Monster Eyes library:
If asked about dependencies, click "Install all".
If the "Dependencies" window does not come up, then you already have the dependencies installed.
Text emphasized with a yellow exclamation:
If the dependencies are already installed, you must make sure you update them through the Arduino Library Manager before loading the example!
After installation, you're ready to try out displaying some Monster Eyes. Each guide page will walk you through the hardware setup for each option with example code.
