Imagine your alarm goes off, and due to a late night you hit the snooze button and get right back to sleep. You realize you’re late for work so you punch a few buttons on your phone to call your boss to tell him a story about how you got a flat tire. You quickly start your car with the remote starter and set the alarm for the house.
I bet some of you have been in a scenario like that once or twice, but you probably weren’t thinking about an invention that you were using that changed the technology industry: the button!
A button is simply a device you can press to connect two pieces of metal together, allowing a current to pass. It’s extremely handy for all sorts of applications.
This tutorial is for those who want to learn more about how electronics (like buttons) work. You’ll use an open-source micro-controller called the Arduino to make a LED light turn on and off.
This tutorial is for complete beginners to Arduino development, but it also goes well with Dani Arnaout’s tutorial if you’ve already gone through that one.
OK, so keep scrolling that mouse button to get started! (more…)
