As it says in the title. I have been searching but I cant seem to find the answer.
What is the difference between void setup() and void setup(void) as well as void loop() and void loop(void)?
Absolutely nothing, in modern versions of C and C++. Specifying no arguments is the same as specifying
In old versions of C a function with no arguments took a single implicit
int argument or allowed you to specify the arguments on a separate line, but no one uses anything like that nowadays.
