This is LED matrix:
-1x3 LED display that can display up to 3 characters in 7x5 resolution
-a character can be inputed into the serial monitor and will be displayed on the display
-a button to turn on and off the display
I made this all by myself! (However I did watch tutorials on how to use some of the components, I linked all my help in the comments of the code)
- Arduino (C++)
- TinkerCAD
