To start this lab, I did not have a working speaker, so I rigged this tool I have from work that can take an input and produce it over a small built in speaker. I soldered a 1/4″ jack to a ground and hot wire to put into my breadboard to replace the “+” and “-” terminals of the speaker.

Playing tones and the most depressing renditions of Twinkle Twinkle Little Star and Seven Nation Army…
These were a little tricky to find the proper delay times in between certain notes. So I just kept guessing and trying different values.
Now with a speaker … and a more complex example using pitches.h…
