Arduino IDE Preparation
To prepare the Arduino environment for programming the Pro Trinket, follow the instructions on Tony DiCola's guide to setting up the IDE for the Pro Trinket here:
For best results, use the latest version of the Arduino IDE
Required Libraries
For this project, the LED matrix backpack, animations, and tone libraries need to be installed. Find them below.
If using an earlier version of the Arduino IDE (prior to 1.8.10), also locate and install Adafruit_BusIO (newer versions will install this dependency automatically through the Arduino Library Manager).
Adafriend Software
When you have finished readying the IDE, copy and paste the code below into your IDE window, select Pro Trinet 5V, tinyISP as the programmer, and upload!
// The Adafriend sketch is derived from P. Burgess's 'roboface' example sketch for Adafruit I2C 8x8 LED backpacks: // // www.adafruit.com/products/870 www.adafruit.com/products/1049 // www.adafruit.com/products/871 www.adafruit.com/products/1050 // www.adafruit.com/products/872 www.adafruit.com/products/1051 // www.adafruit.com/products/959 www.adafruit.com/products/1052 // // Requires Adafruit_LEDBackpack and Adafruit_GFX libraries. // For a simpler introduction, see the 'matrix8x8' example. // // Adafruit invests time and resources providing this open source code, // please support Adafruit and open-source hardware by purchasing // products from Adafruit! // // Eye algorithm written by P.
