I am fairly new to the Arduino, I have been exploring lots of basic tasks with it recently and I feel I want to move on to something a bit more advanced.
I have two things I would like to do, firstly, I want to take follow this tutorial: http://kalshagar.wikispaces.com/Arduino+and+a+Nintendo+DS+touch+screen to get a DS screen to work with the Arduino. As far as I can tell the tutorial seems OK but my question is about the Touch Screen connector breakout which can be found from sparkfun here: http://tr.im/FvdT. I am in the UK and I'm not really willing to pay for the postage/wait for the delivery when I can probably find something like it in the UK. So, is this (from eBay) http://tr.im/FvdL the same sort of thing?
Secondly, I want to play sine waves / audio using my Arduino. I found this guide/article: http://www.uchobby.com/index.php/2007/11/14/arduino-sound-part-2-hello-world/ but as far as I can tell it explains how to create square waves and not 'smooth' ones. So my question is what components do I need to be able to play quality sounds so 8-bit or 12-bit something like that?
