Sup. I've been a lurker here since 2011. When I started I was very new to all of this. Electronics, software, and mechanics blew my mind. Of those three I gradually began learning electronics and software to the point where I could write Arduino sketches and understand the essential parts of most electronics datasheets (with mechanics seriously lagging behind). And I was a happy person. I then fiddled with more Arduino and even got myself a Raspberry Pi. A bit earlier, I had made a robot that was capable of finding and extinguishing candles.
