LOL! I must admit that I used to scorn those durned kids using Arduinos to do the job of a 555. But then I pulled my head out of my ass and realized that times change, nowadays a microcontroller is as cheap and common component as a 555 was when I was a snotty kid, and the new-fangled "maker" movement with its Arduinos and serial-controlled addressable LEDs and conductive thread is keeping younger people designing things and making them instead of just being dumb consumers. It's all good stuff! And once I got a better idea of how much it costs to keep an engineer breathing for an hour, I also realized that it often makes more sense to overkill the heck out of a task with a $20 micro board than it would to spend even a half hour longer doing it the "right" way.
