Run UTFT_Demo Example using Arduino MEGA 2560 Board
      For UTFT_demo example open “UTFT-->example-->arduino avr-->UTFT_Demo_480x320.ino.” 
Note:you must have to put “UTFT” and “UTouch” folder in to Arduino libraries folder like shown in image.before this remove the older "UTFT and "UTouch" folder from same directory if present. 




If you don’t have per-installed Arduino IDE go to Download Arduino IDE
Now open UTFT_Demo_480x320.ino example and select the board Arduino mega.go to"Tools-->Board-->Arduino mega 25260" like shown in image below. 
Now compile the sketch and run sketch on board.



Arduino Code:

#include <UTFT.h>

extern uint8_t SmallFont[];

After successful compiling plugin display on arduino mega board and attach it with desktop or laptop and select the COM port generated by arduino mega board from “tools-->port” and  upload the sketch on Arduino MEGA 2560 board. You can see the some graphics on display.

    how many pins on the arduino mega are usable AFTER i plug this screen in? will i have enough pins left to connect a esp and a few sensors?

      no any extra board required for this display. you can directly connect with mega or due board.
