Simple Touch Screen Interface

Data & Observations
           The hardware has been built and the microcontroller loaded with the software, so let's take a look at how the system functions. The video below will demonstrate how this interface works.

           It looks like the system works rather well. The system knew the difference between the idle (not being touched) and touched states by output the X and Y coordinates of a touch when it occured. The current 1024 points for each axis seems a little too large, but it shows how accurate we can get with pin-pointed spots on the screen.
