Arduino is a software library for AVR microcontrollers (and others). It is aimed at fast prototyping, sometimes at the cost of performance. It has extensive libraries and software for many popular ICs. Elitists will hate on Arduino, but that's mostly because they don't want you to be successful.
Convert Uno code to ASM
apt-get install binutils-avr
compile program in IDE. find .elf file (was in deb 9 /tmp/arduino-build.#####/) (can look at verbose arduino compile window)
avr-objdump -S code.ino.elf > output.asm
See gas sensor, or ph sensor in 2019 projects for more details
