Arduino XPT2046 Touchscreen Calibration and Coding - ILI9341 LCD with XPT2046 Touch screen

A touchscreen makes a great user interface for your Arduino projects. The LCD panel lets you create dials, and instruments that you can then control using buttons, sliders and anything else you want to code.

In this tutorial I'll show you how to write a simple calibration function so you can quickly map your touchscreen data to the screen coordinates and then show you how to monitor for touch events and create a simple user interface button.

You can easily get hold of one of these touchscreens at Amazon or eBay.
