Adafruit Mini 8x8 LED Matrix w/I2C Backpack
Details
James will show us the mini 8x8 LED matrix, its associated I2C communication bus and some code to bring it to life! Two of these mini-matrix placed side-by-side can simulate eyes. With the proper animations you could simulate emotions, add life to a project, make something cute or mean, the choice is yours!
If you want to get one before the class and build one yourself (during the class) there are links below.
