4-Wire Touch Screen Interfacing with Arduino

1. Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching.

This Tutorial shows how 4-wire touch screen can be interfaced with microcontroller

Step 1: Components Required

1. Arduino Board

2. Touch Screen

3. Connecting Wires

Tools Required
