Few things to consider : Each variable in your program take memory, try to use the smallest datatype ( don't use a float if you need an int for example). Eliminate strings Reduce the usage of array Reduce your code size by using function for redudant task Avoid using digital and analog red/write. Use port manipulation instead (link here) Modify library to ...

Researching a little and found the solution! In addition to capacitor 104, its necessari need to add a 10k resistor by connecting the 5 volts to pin 1. This is the link of the GitHub project where I found the solution with the assembly scheme, I hope this helps somebody else! https://github.com/leonvandenbeukel/Arduino-on-a-breadboard/blob/master/README.md

A Nano and some ProMinis have all 8 analog input pins available from the 32-pin TQFP Atmega328P package. An Uno only has 6 of the 8 available in the 28-pin DIP package. Instead of the bare 28-pin DIP, use one of the 32-pin TQFP parts, on a breakout board, or as a packaged 'system' board; a Promini is the 328P with resonator and voltage regulator, connect to ...

No, this is not possible. The datasheet of the ATmega328P states it has: 8-channel 10-bit ADC in TQFP and QFN/MLF package 6-channel 10-bit ADC in PDIP Package If you want to use a bare chip, it won't be possible with a PDIP package.
