With all the installing, connecting, and uploading done and out of the way, you should now have a blinking LED on your Arduino Uno. That’s not to say you already fully understand how it all works—because that would kind of defeat the entire purpose of this book. But now that we’ve got something to blink and know that we can make it work, we might as well jump into learning the basics of programming the Arduino with our first project. By jumping right into how the code works, we can move from hacking together lines of code that somebody else gave us to actually writing them ourselves.
