hii, I ran your code and it showed me the following error message

Compilation error: exit status 1

I'm using the latest arduino ide which is 2.1.0.What is the reason for this?

#error "This version of Arduino is too old"

sorry about the misleading error message, it's actually the esp32 arduino core version that's too old
