I stumbled upon this video, looking for something else actually, but I found it very appropriate for class. It’s a noise box that makes sine, sawtooth and square tone just like the ones we saw in clas last Friday. It can produce different frequencies and pitches of these tones. I think all it’s made of is an arduino, a box, some LED lights and a battery. Now I really want to make one for myself.
