You can dive into the sketch to see how the colors are being manipulated to create the different animation sequences. Now just upload the sketch to your board and watch the different effects. if you've got 3 RGB Matrices connected to the Arduino, change the variable from 8 to 3. This should be changed to the number of boards you have connected to create your frame (i.e. The only thing that needs to be changed before uploading the sketch to your board is the NUM_BOARDS variable. The sketch is commented pretty well so it'll be left to you to figure out what's going on. Start Arduino up (or restart it) and navigate to File->Examples->RGBMatrix->RGBMatrixDemo. Once the library is installed, close the Arduino IDE if it's open. The quickest way to get started with the RGB Matrix library is to check out the demo sketch that's included. Keep sliding up to 8 matrices onto the frame. The next RGB matrix just slides right onto this connected. The wires should be connected to the female header of the RGB matrix, leaving a male header bare. Make sure the wires get connected to the Female Header on the RGB MatrixĪfter the Arduino is wired to the first RGB Matrix the rest of the matrices can be attached to create the frame.

Use the table below as a guide on how to connect wires from the Arduino to the RGB Matrix. I found it easier to connect the wires from the Arduino to the first RGB matrix before connecting the rest of the frame. By the way, the 'RGB Frame' is the entire set of connected RGB Matrices.

The library files are inside the RGBMatrix folder.īefore any code can be uploaded the RGB frame and the Arduino need to be connected. After unzipping the folder you should have a directory with a path that looks something like this. Usually this is located in the Arduino folder. Download the RGB Matrix Library and unzip it into the Arduino libraries directory. Once the hex file has been uploaded to all of the RGB Matrix boards, the RGB Matrix Library has to be installed.
Don't know how to do this? This tutorial on using an Arduino as an ISP Programmer shows you how you can upload a hex file to the RGB Matrix board. Download the RGB Matrix Hex File and upload it to every RGB Matrix board. The bugs have been fixed, however in order to use the RGB Matrix Library the firmware will need to be updated on the RGB Matrix boards. While the RGB Matrix library was being created a couple of bugs were found in the firmware of the RGB Matrix itself. 5 Male/Male Jumper Wires (or just 5 normal wires will work too).This tutorial is an overview of the functions in the library and how to use them Because of this we've written an Arduino Library that allows for easier control of multiple RGB Matrices. Stringing a bunch of these boards together would be awesome the trouble is it's a little tough to control the information for multiple boards.

The RGB Matrix with Serial Interface boards are pretty sweet, but there's really only so much you can do with a single RGB Matrix.
