16×2 LCD interfacing with Raspberry Pi

In addition to the familiar USB, Ethernet and HDMI ports, the R-Pi offers lower-level interfaces intended to connect more directly with chips and subsystem modules. These GPIO (general purpose I/O) signals on the 2×13 header pins include SPI, I2C, serial UART, 3V3 and 5V power. These interfaces are not “plug and play” and require care to avoid miswiring. The pins use a 3V3 logic level and are not tolerant of 5V levels.

General Purpose Input/Output (GPIO) is a generic pin on a chip whose behavior (including whether it is an input or output pin) can be controlled (programmed) through software.
