Welcome to Learn about electronics.  Have you ever been stuck in a tight spot when it comes to basic electronics and electricity? Well now, thanks to our site you can use our database of free basic electronics tutorials to learn all the ins and outs of basic technology.

Helpful videos and diagrams are provided throughout the site on how circuits work, how to solder, de-solder, build cable connections, splice wire, and many other important and necessary subjects you will need to become confident in the field of electronics and electricity.

Whether you're a beginner, hobbyist, student, or just want to learn how electronics and electricity work, then learn about electronics is the site for you.

We suggest starting out with the basic electronics tutorials on matter, atoms, molecules and other related modules in the Basic Electronics section to get a good understanding of how the electronics field of function operates.

These tutorials are readily available on other sites and are only meant to help you get started in the field of electronics.

With our database offering over seven hundred different tutorials on everything from basic radar theory to bridge rectifiers, such as the animated schematic of the one shown below, will help you become knowledgeable on the subject in no time.

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

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.


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. 

The modules are offered in PDF format and can easily be downloaded from our secure server. We just ask for a small fee to cover the costs of maintaining the PDF's on a secure server to ensure they 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.
