I am looking into putting sound files onto an Arduino Nano without a microSD card I figured out how to install the sound onto the card from this site
https://github.com/charliegerard/dev-notes/blob/master/arduino/wavFilesWithoutSdCard.md
It says I need to use pin 11 on the Uno but would pin 11 on the nano work or not? I am getting these boards.

Also, does anyone have good speaker suggestions, I'm going with these right now(https://www.amazon.com/CQRobot-JST-PH2-0-Interface-Electronic-Projects/dp/B0738NLFTG/ref=sr_1_6?dchild=1&amp;keywords=speakers+arduino%5D%5C&amp;qid=1607285501&amp;sr=8-6)
I'm not sure if I'm giving enough information so just tell me if I need to provide you with more information.
Uno and Nano uses the same Atmel MCU, so pin 11 is the same on both.
And a for the speakers, Arduino CAN'T driver 8ohms load! You need a amplifier.
