Make Some Wubs
In earlier lessons we made a light
dimmer, let’s use that same knowledge
to change the frequency of a tone
ourselves! This allows us to build the
basics of a musical instrument.
Can you make it so that the speaker only
plays 4 different notes? Can you limit your
programme so that certain frequencies play
a single note rather than a range of notes
e.g. 0-100 = c?
