The button should allow current to pass when you push it down and block electricity when you let it go. An LED stands for light-emitting diode – it’s basically a small light that you’ll be able to turn on and off with your button. This is the microcontroller you will be programming. You can get all of these parts at RadioShack, or you can order them online. The first thing you need to do is get a couple parts. OK, so keep scrolling that mouse button to get started! What Do I Need? 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. You’ll use an open-source micro-controller called the Arduino to make a LED light turn on and off. This tutorial is for those who want to learn more about how electronics (like buttons) work.
It’s extremely handy for all sorts of applications. 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!Ī button is simply a device you can press to connect two pieces of metal together, allowing a current to pass. You quickly start your car with the remote starter and set the alarm for the house. 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. Imagine your alarm goes off, and due to a late night you hit the snooze button and get right back to sleep.
