Here’s the TLDR: My old post on my L298N-based motor controller sucked. And I didn’t want to do a proper write-up, technical report style. So I made a video explaining it.
Ulterior motive: I hate public speaking with a fiery passion, but if even my little brother can do reasonable commentaries on his YouTube videos and I can’t… then there’s no hope for me. Plus, I had to test out a small microphone I got intended for video recording instead of in-camera audio. Verdict? Tragically low gain, and even if it was usable for audio more than 3 feet away, needs a pop filter.
