ELI5

A generation of electrical engineers (over 40 under 60) design everything using a microcontroller called a “PIC” (peripheral interface controller). They are *very* cheap. They perform no security validation.

heck... I'm 25 and I would have used a PIC[AXE] as we learned on those in school.

yeah, my first experience with microcontrollers was PIC too. these days AVR is starting to become more popular, fortunately.

I learned microcontrollers with the venerable PIC16F84 and descendants, way before Arduino was a thing. It took me over 15 years years to finally jump ship to AVRs for random small projects. Please don't use PICs. For anything. There is literally no metric where they are ideal.

I have a question based on a lack of experience. I started with PIC's & we found for low frequency audio, the PIC could generate a pretty decent waveform for what we needed (sorry forgot the hz) When we tried this with the arduino's, It didn't go so well. Has this changed?

When I say it didn't go well, I mean it was a horrible approximation of a sine wave from the arduino, and the PIC did it fairly adequately.

Without more details about what exactly you were trying to do it's hard to say, but assuming you were using PWM, both micros have hardware PWM peripherals that should be more than adequate for this with a simple analog filter.
