Today, you’ll learn to program something your Arduino to play a tune when you press the button! This project uses a buzzer, which is a small piece of technology that makes a little "click" when you apply voltage to it. If you turn the voltage on and off hundreds of times a second, the buzzer will produce a tone, and if you string together a bunch of tones, you've got music!
Have you ever heard the phrase “it’s not rocket science”? Rocket science is a difficult field of study. While you won’t have an actual rocket to launch, in this project you’ll make a program that, when the button is pushed, turns on a light, just like a rocket launch initiator that illuminates a series of lights in preparation for liftoff.
Have you ever wondered how planes are able to see each other at night? In addition to their RADAR, they also use strobe lights. In this simple introductory project, you’ll learn to program an LED to blink on and off like the strobe light of an airplane.
