Output: LED Matrix

What Is It

The LED matrix features a 5x6 blue LED grid that is able to show numbers, characters, bar graphs, pixel patterns, etc.

How It Works

Very close to a digital screen but in a smaller size, the LED matrix can display various information like numbers, characters and patterns by lighting up and off the specified LEDs.
All LEDs in the grid have their own unique coordinates. For example, the LED in Row A, Column 1 is defined as the origin with an ordered pair (0, 0); in this way, we can easily know that the coordinate (2, 4) indicates the LED locating at Row E, Column 3. If you want to show a smiley face on the screen, you only need to light up the LEDs with specified coordinates while keeping the rest off.
