 Bigger Bigger  Smaller Smaller  Reset Reset

I want to help some 5th grade students create a demonstration of how sine, sawtooth, and square waves sound and appear different. Ideally, we would have a simple 3-way switch, a speaker, and a simple oscilloscope to view the waveforms. This does not need to be a fancy synthesizer - simple is best.

I'm wondering whether anyone has recommendations on parts to buy, working code, and/or wiring diagrams (I already have an Arduino and can do  code manipulation as needed if there's a good starter project out there).

Thanks for any suggestions!

An easier option may be to find an app or some software that will demonstrate this on the computer?

I have an app called Electronic TB for iPad/iPhone that includes a wave generator that 'plays' the sound of the wave at a specific frequency.

I agree that a PC-based solution seems by far the easiest.

While a PC or Ipad solution is the best, you could do worse than build one of these to show how the waveforms can be combined to make something more interesting, its also simple enough for kids to build themselves -
