Mini Electronic Projects

Are you looking for a mini project? Or you want to build the circuit diagram with the PCB layout.

Look in my site you may find a great choice.

Why these are interesting?

Mini Projects for beginner

Imagine you need a LED flasher circuit. You have many choices to do.
first, transistors circuit. Second, 555 timer version. And later, Arduino.

Which is better? For me, Easy and cheap is better. I pick transistor version first. Then, IC-555 or op-amp. For Arduino is so expensive for only LED blink.

Who is suitable for these?


  • Those who interested as a hobby
  • Student schools
  • ECE(Electronics and Communication Engineering)
  • EEE (Electrical and Electronics Engineering) students

Also, studying in homeschooling like us

It is a good learning by doing!

If some project does not work. I am sorry to hear that. But you will learn the solution. It is not a failure. But it is another way of learning.

Most circuits assemble on universal PCB Board. Because of cheaper and faster than buying KITs.

If you try to create these electronic projects and get the results out. Please remember to share it with us.
