With our database offering over seven hundred different tutorials on everything from basic radar theory to fibre optics you will be knowledgeable on the subject in no time.

Once you've become familiar with the information contained in the free online tutorials you can even download a module, or a complete set for your own use.  You can do this from our Electronics NEETS Modules page.

The modules are offered in PDF format and can easily be downloaded from our secure server.

With the intention of looking after your best interest, we even offer virus scans and checks on downloads (for a small processing fee) to ensure that your modules are virus free.

The full module/s also contains questions and answers for you to use in challenging yourself as you progress through the tutorials. Not only will this help you learn content easier and more efficiently, but it will ensure you remember the information in the long run.

At learn-about-electronics we aim to give you the foundation knowledge of the broad subject of electronics and electricity. We suggest that once you’ve covered the basics on our website that you search for even more up-to-date material on other sites to expand your knowledge and give you a more comprehensive understanding of the issue, as these tutorials are only meant to start you off in the electronics field.

The tutorials aren’t in any particular order; however each section of our database is categorized as to what material is contained within the modules to give you the most streamlined experience.
