From Software to Electronics

As a Software Developer, for 20+ years, I've been meaning to learn Electronics for about a decade and after many false starts I've been able to finally give it the time it deserves.  My first project was an arduino clock, using 3 volt meters for Hours, Minutes and Seconds (I'd post a photo but I'm not sure how). I learnt lots from it.  The main thing being that you don't get 5V from the pins. The second things was don't buy parts until you know what voltage you'll get from the pins.... 🙄 I guess I need to learn to read the documentation.  It worked out well and I mounted the meters on a slanted aluminium panel which was slotted into an oak base.

One of the things which I struggled to pick up was the interaction of parts in a circuit.  I could understand them in an isolated way but working out how one part of the circuit was affected by another really threw me for a good while. Especially since most books/online articles go from individual parts then to very, very basic circuits to "boom" - complexity without the breakdown.   If there is to be some videos for beginners could you do one or two on that please?  Have a complex circuit, by all means, but break it down (highlight a section) discussing that and then how it relates to the whole.

Anyway I'm hoping to learn off everyone here, I've really enjoyed the 10+ videos I've watched so far, and look forward to watching them all. Bill's instructions are simple and straight forward. Thank you. I don't subscribe to many YouTube channels but I had to for this.

Cheers,

Titch

PS:

If anyone has any Software questions, hopefully I can help.  My experience covers C, C++, C#, Javascript (most of the frameworks).  I've even done lua before but I'm rusty on that.

Hardware and software are complementary. You can simulate hardware in software or you can embody software as hardware. Just as in software you have modules made out of modules all the way down to your fundamental statements so too a complex circuit is made out of modules made out of modules all the way down to discrete components.

Like software a hardware module has an input and/or an output. Just as in software you can think of it as being made out of black boxes. You can use a function (or object) without having to know how it works only how to use it with your own software, so too with electronics.

Some hardware modules are so useful they are packaged in a chip such as the 555 Timer or Op amps and so on.

So is there any complex circuit you want to give as an example?

(I'd post a photo but I'm not sure how)

@robotbuilder I didn't actually see that but thanks for pointing me towards it.  I saw a photo of one in Hackspace magazine and thought I'd give it a go.  I'm kind of glad that I didn't see it beforehand because I learnt a lot more by doing it from trial and error than I ever would have following it.

Exactly this is where I stand at the moment. I mean, I know what a resistor does and also what a capacitor does. But when it comes to how and what measurements they should be to go together... well, I have almost always to rely on those circuit diagrams of others found on internet and even then, as I start, I keep my fingers crossed that the ciruit is not going to be wrong or blow up something. Not lucky always though.

I am interested to know your start points for sure. I had asked on another thread and I received a few PDFs. But during the few weeks that have passed since then, I have never been able to give them the time I should have.

Welcome aboard. You are surely going to enjoy your stay here. 🙂

Life is exploring and learning

@sid give me a couple of days to collate some sources and I'll post them here.

@robotbuilder thanks for your help with attaching files. This was the clock before I added new dial backgrounds with H, M, S. I used a DS3231 to keep the time do if the clock was turned off it wouldn't lose time. The buttons are for forwarding the relevant dial, thereby setting the time. Also used was an ATMega328 with a Arduino bootloader.  I'll find some circuits that bamboozle me.

Cheers,

Titch

That's really cool

If you hadn't told me I would never have guessed it was a clock

What time is it saying now, maybe about 9:40 or so ?
