I'm troubleshooting some code and saw the following line: value = ADC; where value is a float. I'm really confused by this line because: it's not a function as there are no parentheses I don't see it defined as a macro there is no "ADC" register in the AVR I'm trying to understand what it does …

If you are on Windows C:\Program Files (x86)\Arduino\hardware\tools\avr\avr\include\avr\iom328p.h

Is there an "ADC" register?

It's in one of the AVR include (.h) files installed on your computer
