Interfacing a 4-wire resistive touch screen with an Arduino is an exciting project that enhances your understanding of electronics and programming. This guide will walk you through the entire process, from understanding the components involved to connecting the screen and writing the necessary code.

Understanding the 4-Wire Resistive Touch ScreenA 4-wire resistive touch screen consists of two flexible sheets coated with a resistive material. When you press the screen, the two layers make contact, creating a voltage divider that can be measured. The four wires correspond to the two layers of the
