+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.
