Ah yes, my very first diploma...
I've done and studied quite a few different things in my life in the last few years, but not so long ago, when I still was in highschool, I did an electronics technician course, or an ELV technician (as it's said here where I live). At the point I started this course I was already familiar with coding, but the idea of coding something that I could see it moving and acting physically the way I instructed, really fascinated me. Nowadays it's something that feels just natural to me, and I hope I can share alittle bit of this with you...
My own material
Where I'm studying, there's a robotic club. There are people who need to know electronics in order to do stuff. I happen to know electronics. Here I will put some materials I'm creating in order to teach them.
This is still not a "definitive edition", I'll be changing improving this files over time.
Other good tutorials and Guides
I'll put here links to some other links where you can find good material in case you're interested on learning electronics by yourself. If you still don't have any knowledge, I truly recommend you to start with something like an Arduino Uno Kit.
My course conclusion project
That's one thing that gave me a LOT of headache and stress, but also something I feel mildly proud about. The year was 2019, and we had to create a project using Internet of Things (that fully works, or else we wouldn't graduate). This way, we created the Intelligent Recycling Totem.

I won't get to the details of it since the explanation on github, but I want to point how much I learned doing my part of this project. Integration was the main struggle and achieving it, is what makes me proud about it the most. We had a tiny microcontroller named ESP-01 from ESP8266 series, and in order for the project to work, I had to code this little chip to do various different communications simultaneously, sending the proper data from a server to the board controlling the main hardware, back and forth. Not only that our server also had to handle communications with a SQL database and an Android App we made.
In future, as I develop this website further, I want to add ny own tutorials with ways on to how to use this ESP-01, I hope it can be as much helpful for someone, as much as it would have been for me.
