 =====TASK=====
-After exploring, assembling, and testing the intended circuit (1 button, 1 red LED, 1 green LED, 1 speaker- all independently connected to the pi via separate GPIO pins), adapt the provided C code to provide software control to coordinate button presses with speaker activations, and have the also independently-connected LEDs light up or turn off to mark whether the button is pressed/speaker is activated or not.

-Green means button is pressed/speaker is active.
-Red means button is not pressed/speaker is inactive.
 =====GRABIT=====
 To assist with consistency across all implementations, data files for use with this project are available on lab46 via the **grabit** tool. Be sure to obtain it and ensure your implementation properly works with the provided data.
