I am completely new to electrical engineering. I have a software background and have an interest in tinkering with hardware.
I'm wondering what knowledge/engineering skill/equipment is required to add Bluetooth capability to an existing keyboard. The keyboard I own is a Roland EP-9.
I know there is something to do with analog-to-digital conversions. But in terms of what data is being sent to the internal speakers, I have zero understanding how that works. The issue is "I don't know what I don't know", so I'm probably communicating this incorrectly.
I don't expect a full solution, but any links to helpful documentation is greatly appreciated!
Edit: For clarification, I just want the audio output sent to a BT speaker or headphones. Currently it is sent to an internal speaker.
