Well I will update on my own post and post what I know that will get this project of mine going.
4 wire touch screen
Arduino pro mini (for the compact size since this will be in the car)
Bluetooth modem BlueSMiRF HID (need this cuz it will act like a human interface)
break out board the the touch screen
Arduino meets Amruino
And arduinos program to write the code
There is some other stuff like the breakout board for the arduino to hook it up to the computer to burn the code onto the arduino. But Im going to order the boards this friday and get this project really rolling. I have found one project that kinda looked like I want to do put they are using the touch screen as a mouse through USB. I will have to further read though it to see what I can get from that project.
So If some arduino project master can chime in and help me out with writing the code that would be great. I will continue to update this as I find out more info. I just refuse to pay 215 for the mimicsX2 controller to do this project since I have seen this done with the arduino and the HID.
Wish me luck guys.
