![]() ![]() To open this sketch, in the Arduino IDE menu go to File-> Examples->LedControlMS->MakeSpace_ LEDMatrix You can now upload the sketch to your arduino and see what the example does. You can see practical examples of how the different methods work in the MakeSpace_LEDMatrix example sketch distributed with the library. It also includes two new methods, writeString and displaćhar. The updated library created for the Makespace Madrid workshop defines an alphabet/font of characters that can be displayed in the LED matrixes. This instructable only uses the LED matrix methods. The original LedControl library can handle both 7-segments LED displays as well as LED matrixes. If you go to File-> Examples, there should be a tab named LedControlMS with four files inside it. ![]() The new version of the library is available here (chose your preferred compression format: zip or rar) To install the library in your Arduino IDE: - uncompress the library file that you just downloaded - make sure that you close all the open windows of the Arduino IDE - look for the libraries folder inside the folder where you installed the Arduino IDE (see picture) - copy the uncompressed LedControlMS folder (the folder with all its content) inside the libraries folder If everything worked fine, you can now open the Arduino IDE again. The LedControl library has been updated with several new methods to simplify the display of characters and strings. The nice thing about this library is that you can connect up to 8 matrixes together to build larger displays (more about this in a future instructable). You can read a very clear and detailed tutorial about this library at arduino playground. ![]() This instructable is based on the LEDControl library. The LED matrix is controlled from the MAX7219 chip through an Arduino Library. ![]()
