Many Electronic circuit projects in simple ways of learning

Simple electronic projects

Do you want to have electronics skills? The best learning is making a simple electronic project. There are over 250+ posts on my site. I like the simple electronics projects worked surely. You also are like me. Because I know that you need to have a great experience.

simple electronics projects for beginner

Searching they as you want in categories, may be difficult for you.  So, I will show you the top 100 list of projects.

I like small projects using simple and low cost. Like diodes, transistors, digital electronics ICs and more.

They are ideal for…

  • Student schools
  • ECE(Electronics and Communication Engineering)
  • EEE(Electrical and Electronics Engineering) students
  • Those who interested as a hobby. Some are over 60 years old love Electronics too.
  • Also, study homeschooling the same us.

Good learning is to do!

If the project does not work, we learn the solution. It is not a failure, but it is another way of learning.

Most simple electronic circuits, we assemble on universal PCB Board. Because cheaper and faster than buy KITS.

If you try to create these electronic projects with the small circuits. And get the results out.

Please remember to share it with us.

Any Success or failure is a good learning

I tell you frankly that I did not test all the Electronic circuits Projects shown on this website. So there might be some circuits that do not work well as they should be.

Anyone who tests and finds some projects that do not work at all or do not work well. Please inform me so that we will find out together what the problems are.

Anyways, some friends have built some projects as same as those shown on the website. And found that they worked well.

I believe that any success and failure of the projects are all good learning.

      Thanks for your feedback.
      I think that all circuit can be easily built with a few components.

  74. thank you for sharing this topics.codebind technologies offers best internship in chennai for ece students in following platforms embedded system, matlab, VLSI, plc scada .it gives the more practical knowledge.

  75. Hi ElecCircuit, I love all your circuits and look forward to receiving them in the post. Perhaps in the new year you design a variable “voltage/Current” 240V ac and say 1A power supply with panel meters as well, I cannot remember the make but the usa has one but it was for their voltage only “120V ac” (was the make sencore or something).
    I do a little repair work ” as a hobby mostly) and i have a nice 30V 10A dc power supply but nothing for the mains side but i do use an isolation transformer.

    Anyway Merry Christmas and a happy new year. Paul, London UK
