Design render

How it works

Generates the IEEE logo bouncing around in the space. The color of the logo can also freely be changed by the user with the push of a button

How to test

Simply run it and press the button to change the color.

External hardware

No external hardware was used. All that is needed hardware-wise is a laptop to run and display the output.
