In this third part<\/strong> of the 16×32 RGB LED panel<\/a><\/strong> hookup guide, we will run some demo sketches with Arduino Uno to display basic text and animation on the 16×32 RGB LED matrix. These demo programs use Adafruit’s RGBMatrixPanel Library<\/a>\u00a0<\/strong>are found inside its Example<\/strong> folder. The wiring between the RGB panel and Arduino Uno is discussed in detail in the previous parts of this 3-part tutorial.<\/p>\n

After wiring up\u00a0the RGB panel to Arduino Uno through the connector shield, it’s time now to run some text and animation graphics on the RGB matrix panel. This would first require\u00a0the following two libraries to be downloaded and installed.<\/p>\n

Adafruit GFX Library<\/a><\/strong><\/p>\n

Adafruit RGB Matrix Panel library<\/a><\/strong><\/p>\n

There are multiple ways of installing these libraries to your computer’s\u00a0Arduino IDE tool. Please read this installation guide<\/a><\/strong> from Arduino website if you haven’t experienced it before. The RGB Matrix Panel library<\/a><\/strong> has built-in routines to illuminate selected pixels, construct line, rectangle, and circle, and print alphanumeric characters in two different font sizes.<\/p>\n

After the succesfull installation of the above libraries, we can now try out some of the examples included in the library package. On Arduino IDE, load the\u00a0testshapes_16x32<\/strong> example from\u00a0File\u2192Examples\u2192RGBmatrixPanel\u2192testshapes_16x32<\/strong>\u00a0and upload to the Arduino Uno board. This example illustrates how to draw pixels, rectangles, and circles with chosen pixel color at specific locations. The program ends with printing some 5×7 pixel size text characters along two rows of the RGB panel. Power up the RGB panel and Arduino Uno and observe the program out in action.<\/p>\n

There are three more 16×32 RGB examples included in the library package: testcolors_16x32,\u00a0plasma_16x32,<\/strong>\u00a0and scrolltext_16x32<\/strong>. Because the Arduino pin assignments implemented in our RGB connector shield to connect the RGB LED panel match with the default setting of these examples, they can be just run by simply uploading\u00a0to the Arduino Uno board.<\/p>\n

These RGB panels have unlimited applications. In my next article, I will write about constructing a colorful real-time clock display plus thermometer and hygrometer. Stay tuned!<\/p>\n
