We use monitors every day, on our phones, computers, tablets, and TVs. The displays on most present-day monitors are composed of millions of pixels, short for picture elements. Pixels are tiny points that the computer can light up in different colors; all the pixels together make up the text, images, and videos on the screen.
In this project, you’re going to build a simple monitor using LEDs. You’ll expand on your work with blinking LEDs and learn to use custom functions in Arduino. Finally, you’ll learn how to display secret characters on your very own Nine-Pixel Animation Machine. You can see ours in Figure 3-1.
