This is a REVIEW and a quick tutorial with code Included!
Step 1: Upload Library to Arduino IDE
Go to https://github.com/prenticedavid/MCUFRIEND_kbv = if you have the same library as me, IF YOU HAVE ADAFRUIT LIBRARY THEN UPLOAD THAT
Go to Arduino IDE and go to Sketch >> Include Library >> Add .zip Library and choose the library you downloaded from GitHub.
Step 2: Upload the Code!
Download 3.5 TFT DEMO from this page and open it with Arduino IDE.
If you're using Adafruit LCD then change the <MCUFRIEND_kbv.h> from the top of th page to: <Your_Library.h>
Step 3: Wiring the Display!
Its EASY! Just put everything into the board. If you don't understand then look at the schematics.
