I'm making a system with only LEDs, resistors, cables, microcontrllers and of course code. I am calling it The LED project.
The LED project consists of simple electronic circuits (having as major parts one microcontroller and some LEDs each) wich with code are havig life. The code cleverly uses the restricted parts to make spectacular pieces of art.
you will ned this base for rpi pico (arduino coming soon) here is the google drive link
Upload the code to the pico
Connect 3 LEDs to pins 13, 14 and 15 respectively
Run the code
(optional)Change the code so that you like it
Enjoy
