Old School I/O without 'Arduino' !!!

The last time I bought Arduino nanos, I paid about $2.60 ea, quant 10. Just finishing off a PID controller for a hydronic circulator control using one. Got a wireless irrigation controller up next. Love these things: cheap, plenty of I/O and a decent code space so you can actually get something done. And there's a makefile build environment so you don't have to depend on that IDE.
SilverSolder:
Yes, a cheap Arduino Pro Mini or a Nano is perfect "glue logic" for many circuits, and instantly adds a whole bunch of "nice to have" functionality to any project.
The IDE isn't even that bad, for small projects. :)
NiHaoMike:
Then there's PlatformIO, if the official IDE isn't good enough. Last I checked, the official Arduino IDE doesn't handle multi architecture systems (e.g. Arduino Due + ESP8266, each part done as separate projects) very well since there isn't a per project architecture setting.
SilverSolder:
Yes, it is definitely irritating that the hardware settings cannot be saved with each sketch in the Arduino IDE.

Thank you, and for the following comments by others. I understand that they can be quite cheap, but maybe you missed my requirements! If I was 'prototyping' a specifically programed 'device', that may or may not one day be put to sale as a fully self contained Unit, then all is well. (And ignoring such programming languages, & 'flashing' chips etc.). I 'likened' my design to be 'like' a P.L.C. (Programmable Logic Controller unit), with a graphical user interface for circuit/control/design layout, to be a 'programmable' substitute for a multitude of applications/systems from a PC/Laptop, communicating to various 'real-world' I/O boards for various digital/analog interfaces.
If I survive the end product, (including the 'real-world' process control interfaces), all will be posted for free! :P
