After five hours of coding I finally got the volume knob to work! This was definitely the biggest hurdle for this project, at least I hope so.
Thank you to those who run the AI over at https://www.blackbox.ai/ that assisted me in learning and writing Python code. WIthout the AI I would have been bugging lots of people for far too long to get to this point. 🤣 I already feel like I had! With that…a HUGE thank you to the real humans of the https://forum.core-electronics.com.au/ forums @Michael @Pixmusix @Jeff105671 and cheers to @Robert93820 for the forum help. WIthout them I would not have completed this step.
