Arduino 8x8 Dot Led Matrix Scrolling Text Calculator

Hi,

I do it because i need a calculator for my girl friend (i'm preparing a gift for her :))

Anyway, it's easy. I attached standart code for arduino 8x8 dot matrix 7219. Then you can create your text with my excel file and copy codes from the excel, paste to the arduino code editor. But then you have to do something, because i don't finished all codes for excel file. You just copy codes from excel, paste to an editor (i'm using notepad++, it's my personal choise) and add "{" characters to all start of rows and add "}," to all end of rows. That's it!

How you can use the excel file? Very easy. When you open the excel file, you will see some texts (it's written with "1" characters. It's an example and you can change it. Then you can use "left" and "calculate" buttons for scrolling and codes. Thats it. Please try, if you cannot use, write to here, i can help you.

Have a nice day.
