content: Hey guys. So, I have done a lot of playing around with kits and dev boards for micro's and similar, and have had lots of success for the simple things... digital things.. but I really don't know any of the theory. I can understand 1's and 0's extremely easily which is probably why I've done stuff with micro's... idk. But ..Ok, forget my ranting, my question: I'm looking for a beginners guide to electronics. I suppose I should start from the beginning .. so I pick up any of the theory that I may have missed learning the very basics (lighting a led, 555 flasher, the stuff a kid would do).Now, I know I need to learn analog stuff, but I only want to learn a bit more than the minimal amount as far as analog goes (unless I can get myself interested in it). My goal is to have enough knowledge to design an ARM dev board by myself. All of it's just for a fun hobby, and I think it would be really cool to have my own little ARM board. I REALLY like custom stuff, that's probably why. But hey, I have considered becomming an electronics engineer (i'm that young, but right now i'm planning to be a programmer.. anyway, getting off topic and ranting, sorry), so it would be great to learn it early.Please forgive my ranting and getting off topicCant help it. Thanks!

content: ARM, for a beginner? Homemade? Sure you aren't mixing it up with AVR? Two completely different things. As far as beginner level things go, don't know anything about your location and what you might have available, but try your local library and see if you can grab a book introducing the basics of electronics (Like what are resistors, capacitors and so on used to). Dave's Electronics Tutorials playlist is good toohttps://www.youtube.com/playlist?list=PL3C5D963B695411B6, tho a bit more advanced.

content: Nothing wrong with wanting to specialize in digital design, but you should learn more than just more than the basics of analog design. At the very least you should get up to the point of having a solid grasp of operational amplifiers (in my opinion). The reason for this is because, even though we might have a digital specialist, we all need to understand the design and how the parts interact together. Look at the debounce issue for example, from a digital point of view a button is on or off, but that's not how it works in the real world. If you like programming, but also want to be involved in electronics maybe you should look at embedded design.Have fun anyway!

content: Thank you all very much. To clarify, I am talking about ARM. I was saying that I want to learn enough to be able to design my own ARM board. FYI, I know SOME of the absolute basics (resistors limit current (not voltage if i remember correctly), capacitors store power, transistors are like a switch that can be controlled with a signal) etc. I have basic ideas of what they are, but need to learn more in detail. As far as learning more than the basics of analog, I though op amps were part of the basics but what do I knowBy the way, I have not used an AVR at all but I have played around with PIC a tiny bit. I of course prefer Arduino.I will check out your links and see what I can do. Thanks again

content: No, I enjoy it as well.. I wrote that when I was really tired, had been up all night, thats probably why it sounded that way.

content: This is an excellent book by a very cool guy. In fact he has a property of LEDs named after him "The Mims Effect" which is where he proved that you can use an LED as a light detector as it produces a small amount of electricity when light that's in its wavelength range is shined on it.http://www.forrestmims.com/Everything is hand illustrated by him and in a very memorable format.You might also want to watch some of Afrotechmod's and W2AEW's videos on youtube.W2AEW's videos can get pretty advanced sometimes but there are a lot of good videos on the basics.Afrotechmod's videos are also very good and go into a lot of how parts work.

content: Quote from: sci4me on June 06, 2014, 10:53:38 amAll digital signals are sent along analog wires, with their finite and nonzero resistance, capacitance, and inductance, and the associated propensity to radiate EM waves, as well as to capture EM radiation. The lines are driven by analog circuits, with limited slew rates, limited output voltages and currents, etc. If you can ignore the analog details and simply treat things as ones and zeros, you should heartily thank the designer(s) somewhere along the way who did a good job of handling those analog details for you.Many of the nasty problems you run into in a digital design are really analog problems. Crosstalk, impedance mismatches, RFI susceptibility, etc. can make a digital device "flaky". If you don't have the analog background, when your digital circuits start misbehaving, you won't have the necessary tools to diagnose and fix the problems.Even if you're only designing boards for digital products, you've got to know enough about analog to keep yourself out of the danger zones. It may help if you run everything really slowly, but that's not a good strategy for high performance.A few rules of thumb may keep you mostly out of trouble if you're treading well worn ground making an ARM board that's similar to existing ARM boards. But to do significant design, you should gain at least a reasonable familiarity with inductance, capacitance, transmission lines, simple analog filters, impedance, frequency response, etc. That's especially true if you want that ARM board to interface with the analog world.I've been out of the introductory literature too long to recommend a specific introductory book, though. Perhaps "The Art of Electronics", by Horowitz and Hill, but I'm not sure if that's what you're looking for.

content: Quote from: Stonent on June 06, 2014, 10:55:08 pmThis is the best book any beginner can get.When I bought it about 30 years ago, I couldn't believe how clearly it was written.I'm glad it's still available.

content: Quote from: AG6QR on June 06, 2014, 11:19:37 pmGood points indeed, are those things not .. basics? or, slightly more than basics i suppose? IDK. Either way, you're right I do need to learn them.

content: I found this book -Electrical Engineering 101- to be a very easy to digest introduction to theory. I highly recommend it!

content: Quote from: sci4me on June 06, 2014, 09:42:38 pmGood I'm pleased you enjoy Electronics, when I first started out I got this book it's old , but I think you can still get it , it's called "build your own test equipment by Homer.L.Davidson and a right to date book, called "homebrew cookbook" by Eamon Skelton EI9GO, this one Eamon builds everything modular, so you can take a sections of previous projects and use them on others, he goes through making PCB,and etching, construction, to making a programer , very enjoyable.Paul
