As I said in my previous post, I don't have much knowledge in electronic.
I know some basics as Ohm's law, Kirchhoff's circuit law, I've heard the terms "PNP" and "NPN" without really understand the point of those transistors... but it was always in the context of some problem given in physics courses.

In this blog, I will not give you the theoretical basic knowledge, a lot of website will do it a lot better than me.
I will only talk about my problems, solutions, mistakes, epiphanies, and discoveries.
I will also talk about the electronic pieces I bought on some cheap website :)

Below, some laws that I tried to understand by reading a looooot of websites, and which will be taken as acquired for the next posts.
But remember, it's not because I know those rules that I know when to use them ;)
