I have read and researched a lot but can't quite get the answer 100 per cent. Long story short I'm modifying some PC Speakers so the Amplifier is seperate. I plan on controlling this with an Arduino, Digital Pot and LCD Display.
After identifying that there were Double Gang Potentiometers used (I saw Rotary Encoder mentioned and that threw me off my confidence) I went about researching replacing them with a Digital Pot and saw this Post: Controlling a Digital Potentiometer Using SPI
Now if I was to remove the existing Analog Pot and connect the Wiper from Dig Pot in its place would this work? I have a feeling I'm missing something related to the power requirements.
