Acerca de: Just getting into the microcontroller craze. I used to do this sort of thing building circuits for 8 bit microprocessors back in the early 80s, so this is kind of like reliving a bit of my childhood. Back then I programmed in machine code, so now I am teaching myself C for the Arduino. It's a fun way to waste some time, and it's nice to have a hobby. More recently now, I am getting into printed circuit board design so that I can take what I make with the Arduino, and make stand-alone circuits.
