Agreed. I really love the modern microcontrollers like the Arduino and tiny embedded computers with GPIO like the Raspberry Pi or Galileo because they make it so incredibly easy to turn a hardware problem into a software problem. And writing software is super easy, even if you’re not an expert. You can just keep trying another solution over and over and all you have to do is push a few keys on your keyboard.
