After playing around with card10 a bit, you want to learn how to write your own software. Even if you have never programmed before, it is super easy to make some LEDs blink on card10 :)
### [tl;dr](/en/tldr)
Spare me the details just give me the links to the docs!
The easiest way to make some LEDs blink is using python. There are two ways of executing python code: Using an interactive command line, and saving `.py` files on the card10. The interactive command line is very practical to try out python commands, and debug '.py' files. Directly saving .py files makes the scripts you write available when you have card10 disconnected from your computer.
