    I don’t think that actually answers OP’s question. If all it does is vibrate then it doesn’t need any software. It presumably just has a single button that turns vibration on/off and maybe cycles through vibration levels. A dumb circuit without even a single chip in it could do that.

      Ah, but what if you want it to vibrate to the beat of your favorite song? Did you think about that?

      I’m just guessing here, but it’s probably for battery management and wireless charging, which are tricky problems you’re not gonna solve with a 555. I generally trust EEs to not put MCUs where they aren’t needed, so this must have been the cheapest/easiest option.

        As i said in my original post, “A dumb circuit without even a single chip in it could do that.” Vibration units can literally just respond to voltage. It’s how electrical devices worked before chips, like old pinball machines and old radios. It works just like how a standing fan works - there’s a mechanical motor, and you literally just need to attach plain copper wires onto the motor’s contact points and stick the other ends of the wire into the slots of a wall power outlet.

        You don’t need a chip in a vibration circuit. Hell a potentiometer is more than sufficient to give you different levels of vibration

          I don’t know why I’m replying this deep to play devils advocate for some stupid knife, but I could see a situation where you haven’t completed the research on optimal frequency and ship it out while that’s ongoing. Maybe the window of optimal frequency is narrow enough, or unknown enough, that it’d be difficult to calibrate a potentiometer such that the end user could find that ideal point.

            I want an update that let’s it play audio files by vibraing the blade.

              My only acceptable IoT scenario is where all hardware is open and we can indeed flash music software onto it.
