a.saji, I think that applies to almost any job. If you love the work then it can be fun. I agree with you on just wanting the title. I think, well it used to, take a certain mind set to be a programmer. A lot of people might be able to do it, but some just understand it better.

@a2: Yes its fun as long as you really love it. If you are just a programmer for the name itself then you will not get the maximum out of it. Loving does include work pressure, depression and late and weekend workings as well.

Yes a2 I do agree with you regarding the programming and also I would like to add, go with the new tech is a must or else it is essential to be update the knowledge up-to-date cause that programming is updating every day.

@roshenac: Yes even I too feel the same. Then you can customize the way you want it rather than listening to a robot instructing you based on what it wants.

@William: Yes programming is fun and you will learn only if you do programming but right now programming has been made very easy and anyone who can think of a logic can do it. For me I feel that is not real programming. Real programmers do know what the business logic and the programming logic is. I feel it's the software programming that has been made easy. It's the hardware programming that has not being changed over the past few years.

Doing programming is a good way to learn how to do programming, and possibly to become good at it. Developing and creating ciecuits, and designing circuits to accomplish different functions is a good way to become skilled at that. Just like learning to play the drums very ell will probably never make me a good guitar player, the two skill sets are fairly different.

I have not written programs in any current language, but I have created the specifications for a few programs, which included descriptions of the screens, I/O functioning, the equations used for calculations, and what data to be saved. The specifications are typically done so that any program could be used, depending on the customer and the programmer. Creating such a specification does demand a very detailed understanding of what a machine must be doing and how it must be doing it. Writing the code requires a good grasp of a given language and skill at implementing instructions sets. Quite different skill sets. Many programmers could not design a circuit to illuminate an LED from a 9 volt battery.

William K, I do understand your argument and largely agree. I have a parts bin full of TTL DIP ICs. Ring counters, logic gates, op amps, etc. I sometimes imagine the projects I could build with them. But it is so much easier to just do the wiring in software. And, hey, how about those Programmable Systems on a Chip (PSoC)? So I'm torn between the "primitive" ICs of the 1970s and today's options. I was out in the forest today cutting my own heating fuel for the winter. I'm even thinking about going off grid. I play phonograph records. Yet I check my iPad for stock quotes.

Yes, even though Arduino is Open Source, companies do make a lot of money promoting it. Buying an Arduino from them is easier than building one's own. Red Hat makes money on Open Source Linux. As an experienced, mature engineer, it would make no sense for you to do a company project with an Arduino. But what about those high school students I met a the Maker Faire? The body of knowledge is great and the learning curve is steep. Is the entry point for their education the Arduino and Raspberry Pi -- or is it breadboarding TTL and op amps? I have no opinion and no degree in education. I really liked Elvin Lin's proposed solution below as it is very modular and simple, yet uses high level components. But you are correct in that that is not really engineering.

It's an interesting topic for discussion and Gadget Freak is a great place to discuss.

@78RPM, whileI could not derive the circuits for the monitor that I am using now, I have actually built a magnetic deflection scope, without assistance from other than the RCA tube manual. And I would probably understand the circuitry for tyhis flat-screen monitor if it were available. 

I would not go so very far as to say that the audio desk tray project could be done with 555 timers, but the record/play chips on board circuit is a worthwhile approach. The big gripe about doing everything with that arduino is that even systems that would be both better and much simpler done with discrete components are presented as programmable things, with no real engineering involved. One publication must actually be owned by the arduino folks, since almost all of the projects with any electronics are done using an arduio board, or a collection of their boards and modules. It is certainly OK to tout one's own product, but being honest about doing it has more integrity.

Thanks for the suggestion. One reason I used the voice recording modules was that i liked the idea of the message being played back in your own voice rather than a typical robot voice. Made it more personal

As a programmer I am a lot more interested in the software than the engineering. I find that the Arduino is a nice step first in to learning a bit more about embedded systems which is why I use is.
