I see so many questions, including some of mine, in which a particular implementation is described and help is requested.
And, without fail, the team of MCU pushers comes around and strikes down any solution which does not use the MCU.
This occurs without even considering the original design requests.
A good example is I asked for a way to wirelessly send data. The question was even downvoted and all the information I got was to 'USE A MCU'.
Well, with only two chips I was able to solve my problem. Of course, I did not use an MCU. I stated in the question my reasons for avoiding on in this case. But, inevitably, I am given the normal responses: "USE A MCU! WASTE OF TIME OTHERWISE".
Just today there is a question regarding making a clicky sound with a relay. Of course, the gang comes around again. "USE AN MCU". Why? For god's sake, the OP is requesting a retro sound via analog means (relay or turn-signal clicker). It's not like he asks "How can I make the clicky sound". No, he asks "I want to make the clicky sound with a relay, how can I make it louder".
Why is there this great push for all solutions to all problems to be solved with an MCU? They are arguably less robust than most direct solutions, and they abstract the problem space to an area which may not benefit the person asking the question.
I understand that MCU's are powerful tools that can do great amazing things.
- light up a matrix LED display to music;
- control a remote car or drone;
- control a smart fridge;
- control a camera;
- track my energy usage and wirelessly relay this to the energy company;
- run my thermostat with my time and temperature preferences;
- send sensor data in real time to central hub;
- control the timing of my garden watering schedule taking into account rain and sunshine;
- analyze plant controls and implement feedback;
- and a million other practical examples
But I am getting a little tired of every question in which a particular implementation is provided being rebuffed with "USE AN MCU" (without even analyzing the originally presented idea by the OP).
Can we please judge each question on its own and not automatically assume the user is an ill-informed idiot who should use an MCU?
