Using our range of LED Dot Matrix Displays is easy thanks to our Arduino library and included interfacing hardware, however creating customised graphics has involved combinations of line and pixel control commands to achieve the desired output.
However this process has just become infinitely easier thanks to Freetronics forum member jedihermit whose Microsoft Excel macro can be used to easily draw images, with each LED being represented by a cell in the spreadsheet.
Once you have drawn your image in Excel - the required code for your Arduino sketch is created and can be copied from a tab in the Excel sheet. You then simply copy this code into your own sketch to control the DMD with your creation.
This is a fantastic piece of Excel work - so to download the Excel file and discuss this project further, please visit the Freetronics forum. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
As used in the example mentioned above, check out our Freetronics Dot Matrix Displays. They're simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics quite easily - and can be daisy-chained together for extended displays.
