While ordering some items on Banggood, I picked up a deal (I thought) on two touchscreens (2.8" and 2.4") with an included arduino uno clone (under $10). I followed Bill's presentation on touchscreens and ran the examples. All the examples worked, except neither screen accepted input. The 2.4" screen displayed all the text in a mirror image. These screens use an unidentified driver chip and I spent a day looking at various Youtube and arduino forums trying to get them working. At the cost of these, not worth more time investment. Will use the 2.8 as a display only! If you buy a touchscreen, look for the ILI9341 driver chip as that seems to be preferred and should give less problems.
