Include the avr/io library so all port commands are understood. Default is 12 bits (range from 0 to 4096) for all chips except ESP32S3 where default is 13 bits (range from 0 to 8192). analogRead inside the for loop always returns zero whereas analogRead outside the for loop returns correct values. It defaults to 10 bits (returns values between 0-1023) for backward compatibility with AVR based boards.e.
