user13355: I have an Uno + WiFi 101 thermometer and I'd like to be able to take it places and easily change WiFi network SSIDs and passwords.  Can I use a TFT screen to make these changes to a sktech or am I stuck using a PC and IDE for this kind of thing?
Can someone provide a sample sketch of what this might look like?  I want to know it's something that's possible before I spend the money on a TFT.
It's possible (let's face it, LIKELY) that I fundamentally misunderstand the capabilities and limitations of the TFT screen.  Sorry for the noobish question.

user10794: A TFT screen is just a screen. You can't modify SSIDs and passwords with it, any more than you can by poking your PC monitor (unless perhaps you have a touch-screen*). To modify things you would need:

An input device (eg. a keypad)
A method of displaying what you are entering (this is where the screen would be handy)
A method of storing the new information. You could store things like passwords in EEPROM.
Code to make all that work.

* Some distributors sell touch-screen interfaces designed to go on top of screens - this might conceivably be what you are thinking of. However you still need the touch-screen, and code to make the touch-screen, and the TFT screen, work.
