Hello! I have been working on trying to learn how to use a LCD, but code that should work gives me an error message where it can’t compile for Arduino Uno, even though it compiles for a ESP32. Here is my code: #include <LiquidCrystal.h> const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2; …

Please post the full error message

So how do I switch to the right library and which one do I switch it to?

it's not the library, but the installation of the IDE

So then do I just delete and reinstall both IDEs? It’s happening for both (the old and new)

i don't know what you mean by both.

The old IDE and the new IDE (I use both)

looks like one is confused about where the compiler is. trying re-installing

Re-installed and got same error message

Did you do a clean uninstall and re-install? Like recommended in this thread?
