A bit of a background so you know what I am trying to achieve and the best way to solve this;
I am installing an Android tablet in my car. Sine I'm integrating the device in to the dashboard, I won't have access to the volume buttons (up/down), which are on the side of the tablet. So, I'm going to solder 4 wires to these button and extend the volume buttons and mount them somewhere suitable.
So now, I want to use something like a [u]rotary encoder[/u] to control the volume. So in other words, every time I turn the knob right the volume up button is pressed and when I turn the volume down, the volume down button is pressed. In other words use the rotary encoder as a close switch circuit to press the buttons.
Is a rotary encoder my best option here? I don't mind programming something with an Arduino and a rotary encoder to act as a press button, however if there is a device already that can do that, I may as well use that.
I've also found this: http://www.ebay.co.uk/itm/Rotary-Encoder-Volume-Control-Board-TK2050-TDA7492-/350480722297 Not sure if it will act as a close circuit for what I need for at all?
Any help is appreciated.
