Hi
Im wondering how to control sound volume via buttons + - and also to stop and play music. Im not so good with elektronic but so far i have done micro usb dock station with mini jack audio output. I have 14k and 17k rezistor. My dock station is working on 360k rezistor. So my question is how to control volume on my phone(Samsung galaxy s3 or samsung galaxy tab 3) using rezistor on micro usb cable. Meaby someone car draw some schema how to do that. I thought that connecting 4 and 5 pin with 14k or 17k rezistor will do something bot nothing happend.
