It's been a long time since I posted anything here, but since I've been making stuff, I decided I might as well share something I've made.

My engineering class is having a Secret Santa thing and I wanted to make a cool gift instead of just buying something, so I made the Owenscope (the guy who's getting it is named Owen, so it fits Razz). Simply put, it plays a sequence of 4 beeps in a row. Each beep has its own individual pitch, set by four different pots. There's an Arduino Nano at the heart of it all. Not too useful, but it's pretty fun to mess around with. I can only explain so much in text, so here's a video:

What a fun project! I assume that each potentiometer is connected to one of the analog pins, and that you use the PWM pin(s) for output? Does it generate stereo or mono output? What inspired you to make this project in this particular way?

Yep. I could've done it a different way and added more pots (and more changeable parameters), but it's good enough as it is. Razz

I didn't use PWM, just the built-in Tone function. For this project, I didn't need anything more sophisticated.

Just mono. I only have mono jacks right now, so that's what I had to work with.

I wanted each parameter to have its own control. I could've made this way more sophisticated and musically useful, but I had just wanted to make a fun noisemaker, and IMO fun noisemakers shouldn't require menu diving and tedious programming to make fun noises.
Fair answers to all my questions; thank you! Also, if your classmate is so inclined, I'd imagine that he could repurpose it into a more complex synthesizer, where the knobs could control things like tempo, tone, and effects.

It already has a tempo control (the RATE pot), although it's rather rudimentary. I'm also starting another sequencer/synthesizer project that hopefully will be musically useful (12-bit DAC, piano-style keyboard, FM synthesis).
