About me

I'm just a simple man who loves electronics. I live in Spain and I've studied electronic engineering in UB, University of Barcelona. ELECTRONOOBS all started as a simple Instagram account where I was posting all my daily projects and homework. I soon started working on this webpage where I’m currently posting new tutorials every day. As you can see, there is a bit of everything. Electronics with Arduino, basic circuits, robotics, 3D printing and so on.
