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

1. Laptop with Arduino Software
2. USB cable

4 wire touch screen interfacing components required

Step 2: Connections

1. Connect X1 to A0 of arduino
2. Connect X2 to A1 of arduino
3. Connect Y1 to A2 of arduino
4. Connect Y2 to A3 of arduino
