Best Free Electronics Learning packages / info on the interwebs ?

G'day all - new at this but dead keen.

It's been 30 years since I played with electronics so I'm more than a little rusty.

I'm hoping someone can point me towards some good tutorials to get me started again.

(Even things like when to wire LEDs for example in parallel and when in series.)

Anyway I have searched the forum and not been able to find an answer, my apologies if I've missed it elsewhere.


What country are you in ?


raschemmel: The best one.


Thanks LarryD - much of that is specifically arduino though and while welcome, isn't the more general electronics basics and circuit design stuff I'm looking for.

Can you read a datasheet and a schematic ?

Can you read ? ( your post title ?)(ADD?)

List the main general topic categories of electronics as you know them to be ( or think them to be) .

hehehe (or should that be hahaha). I can read just fine, but typing is a whole other issue.

I'm pretty good with circuit diagrams / schematics. Well, up to the point where complex electronics come into it anyway.

Main general topic categories? I'm not even sure I understand your question.

I will probably be able to get my head around the coding for Arduino but it's the design of the actual circuits for projects which I envisage being more problematic. For example working out when pull up and pull down resistors are required, and what values.(just as an example).

To indicate perhaps my skill level to some extent I can solder, I can use a multimeter, I can't use an oscilloscope.

Good news: I have a science degree.
Bad News: Major in Zoology is not particularly relevant here.
Worse news: I also have an arts degree.

Around 6 months ago i was in your situation, a little improved now. I never had any electronics knowledge. I started learning a bit by bit by going through Ohm's law and other basic electronics theories.

Also started following all the 'General Electronics' posts in this forum. Most of the times i never understood what the members are talking. So google it and understand the stuff theoretically.

I have certain projects in my mind, if any post comes and that give me hint that i might can use it in my project. So i note down the component buy it from a shop and experiment with it.

One thing i realize that Electronics is an addiction :slight_smile:

Good newa bad news :

Good news is the Arts degree and the Zoology degree give you insight into applications for electronics.
Bad news is you need to learn how professsionals do electronics.

Topic Categories:

1-AC electronics : (all that sinewave , audio, HV and phase shift and VARS stuff.

2- DC Electronics: (90% of the arduino projects , involves Ohm’s Law a lot (which you didn’t mention BTW)

3- Semiconductor Devices: ( all that diode , non- linear , transistor , opto-isolator, triac, mosfet, LED , thryster , solar panel and other semiconductor stuff)

4- Electronic Circuits:( how it all comes together)

5- Microprocessors: (well, obviosly, this is where Arduino comes in)

6- Robotics: (Wasn’t on the list when Heathkits were selling there home study courses in the 70’s , shortly after Intel madd the first Microprocessor (8008) in 1978)

Drone Technology: ( new category, is a subset of Robotics)

Robot Drones/Drone Robots: ( use your imagination)

( correct the typo in your OP)

Getting Started In Electronics

6- Robotics: (Wasn't on the list when Heathkits were selling there home study courses in the 70's , shortly after Intel madd the first Microprocessor (8008) in 1978)

what about Intel 4004 (1971) ? :wink:

what about Intel 4004 (1971) ? :wink:

alzheimer's ?

Thanks all. I found a few and while some are too basic i can get a bit of good info here and there. .. it's starting to come back to me.

Can't wait til my breadboard and pile of components arrives :relaxed:

My Arduinos arrived and they are lonely.

Hey landyvlad, I'm in the same boat as you. Two days ago I came across Autodesk 123D circuits, they have great learning resources. I've learnt plenty over the last couple of days.

Thanks Ninja.....

Learning Electronics, is fun ... if you want to. It will need a lot of dedication and lot of reading and starting over again.

The electronics landscape is ever-changing. An electronics engineer has to cope with learning new emerging topics in diverse disciplines that work together. It all depends on what you want to do and where you want to get to.

For instance, if you just want to do the odd circuit, then basic electronics and some hardware design is fine; if you wanted to take it to the next level and some improve the interface and intelligence of your devices, then learning microcontrollers and software programming is inevitable. That said, this should only add to the fun!

Sparkfun's answer: Where Do I Start? -

However, if you fancy a complete electronics course, then try MITx:


Or MIT's Open CourseWare OCW, it's fantastic that you could MIT education for free (consider donating):

Eric Coates Learn About Electronics is a decent resource online:

A brief course from the electronics club

There is a lot of videos on YouTube that would really help you.
Here are some of the ones I have viewed:




Of course: there is plenty of e-books online, the short list below given you the title and the URL to where you can find them. You can download the ebooks or just view (and bookmark them online).

Practical Electronics for Inventors

Practical Electronics Handbook

Radio and Electronics Cookbook

Inductors And Transformers For Power Electronics

Happy learning and project building!


Thanks to OxSAM :slight_smile:

My 0.02 cents.. :slight_smile:

Dont let something that may look like its specifically for Arduino scare you off.. or think that its of no use.

MANY good rules and lessons on how things should be connected can be learned through 'Arduino based stuff'.

I think the pig-hixx wiring diagrams are a GREAT reference:

Having a good electronics base is good to have! (I wish mine was better! lol)..

but I also believe that working toward a 'goal' and having a real world project lends itself to understanding these rules/principles..

in my footer is a link to the TronixStuff and Jeremy Blum.. I think they have done great work creating Arduino tutorials..

worth a look.

xl97 is absolutely right, work towards a goal and you will learn a lot. My goal was to create an Aeroponic controller and I learned a lot in the process and still learning by building the next version of the board running Atmega in standalone mode.
