IQ Audio DAC+ Rotary Encoder On Raspberry Pi B+
This is a quick tutorial on how to add a rotary encoder to a Raspberry Pi with an IQAudio DAC+. There were bits and pieces of this on the web but nobody has a Barney style tutorial and that’s what this is.
The assumption is that you have a Raspberry Pi and IQAudioDac that plays music. And now you want to control the volume manually.
And I’m making the assumption that when you got your IQAudio DAC that you soldered on the header pins they sent with it. You’ll need to do that. Follow the directions on page 30 of their user guide.
First get the rotary encoder and some female to female jumpers from Adafruit.
