I have a project that I will be working on that includes mounting a touch screen in my car to control lighting. It doesn't need to be super accurate. Basically my idea is to have an overhead image of my car displayed, and the corresponding lights will turn on depending on whether you press the front of the car or the rear. So basically no more than 2-4 zones need to be registered on the touch screen. I really want to find a screen with a decent resolution that is bigger than just 2"-3". Is there anything in the range of 5-6" that will work easily with the arduino?
I have seen several threads of people asking for this. And no real reason is given for why all the arduino screens are so small. So what is the deal? Anyone have any ideas for me?
