The rest of this section will detail the main changes that have been made to this program. In fact, you
should delete the entire main while loop in speaker_tone.c, since we will be replacing it. For conve-
nience, here is the complete listing for the new while loop.

switch_pressed = NULL;

// Wait 50 ms to make sure the switch stays pressed (debouncing)
waitfor(DelayMs(50));
// Check if the switch is still pressed

// Check for a switch pressed. When we detect one, then save off the pin structure
// for the switch pressed, the pin structure for the corresponding LED, and the number
// of the switch pressed.
