Add some action to your coding loop with a blinking LED light.
New Concept: Loops
Computers are great at doing things over, and over, and over, and over again. That’s what happens inside your void loop() function in this program. The computer reads your program from top to bottom, so it reads line 8 before line 9. However, it’s reading really fast, so you’ll usually have to add in some delay to make sure you can see how your program is working.
As you program more, you’ll get better at imagining which line of code is running as you watch your program work on Code Rocket. You might even start to think of the program more as a ‘circle’ than a single sheet of code.
