Sometimes you don't need a full-blown Arduino-type microcontroller for a simple job. This eBay product fits the bill perfectly, is well-priced (I couldn't make it for this price) and it's a whole lot easier than getting an Arduino running. And it is working right now on my desk providing cheap, reliable service.
What's the product? See the video!
On other occasions nothing but an Arduino will meet your needs - but do you really need an Uno or Nano to run some simple sketch? Simple in terms of the sketch but complex enough to warrant GPIO connectivity with the logic that goes with that. What are the limitations, if any? Not much, is the answer. Can it run just like a standard Uno or Nano? Oh, yes!
So what am I suggesting? Watch the video!
eBay is a constant source of amazement and inspiration to me. Not just eBay of course; Banggood, Gearbest, AliExpress and Tomtop are other Far Eastern supplies (to name just a few) that have proven themselves to be honest, reliable suppliers of electronic equipment at prices that we can all afford, even if only on an occasional basis. It's often worthwhile to "window shop" just to see what's available - you never know, that left-handed, Bluetooth-enabled widget you were after might be waiting for you!
