At first I thought it was a parody about overdesign and CV-driven development.
This kind of feedback loop can be done in hardware without even an IC. Or an 8266 microcontroller (2 euros on aliexpress) if you really need WiFi.

I wanted a medication reminder with a blinking light for my partner so that it would come on at the right time and turn off when she took the meds. Could I have done it in pure hardware? Sure. But I bought a Raspberry Pi and we wrote the code together in Ruby because that was faster an easier. It in some sense was an egregious waste of computational capacity, and the parts cost could have been way lower. But it was also 50 bucks and it was using stuff we already knew. Even if I valued my time at minimum wage, "overdesign" was the optimal choice. And I definitely charge clients more than minimum wage.
10 minutes if you start from a code example.
You can make a turkey edible by just salting the whole thing. Or you could bury it under a pile of hot rocks (2 euros on aliexpress) if you really need to get heat involved.
