programming Nextion LCD with Arduino

Hello,

I am Bryan and currently doing my Final Year Project.

What I currently have to do now is to figure out how to combine/code LCD with Arduino.

My group is using ITEAD NX4832T035_011 LCD and ARDUINO MEGA 2560.

I am trying to make the page change after activating the push button (physical button), but i dont know how to code it as i couldn't really find any good post online about it.

Please please please help me, even one small advice will really benefit my project.

thankyou!

For Nextion LCD, refer to this project Nextion LCD communicate with Arduino UNO - Arduino Project Hub
