  1. The GPIO (General Purpose Input/Output) pins on a Raspberry Pi are a versatile feature that allows users to connect and control external devices such as sensors, LEDs, and motors. These pins are located on the 40-pin header of most Raspberry Pi models and can be configured as input or output for various electronics projects.

    GPIO Pin Layout and Functions

    The Raspberry Pi GPIO header consists of 40 pins, which include:

    • Power pins: Provide 3.3V or 5V power.

    • Ground pins: Used for grounding circuits.

    • GPIO pins: Configurable as input or output for digital signals.

    • Special-purpose pins: Support protocols like I2C, SPI, and UART.

    Each pin has a specific role, and the numbering can be confusing. The physical pin numbers differ from the BCM (Broadcom) GPIO numbers used in programming. For example:

    • Physical pin 1 is 3.3V power.

    • Physical pin 7 corresponds to GPIO 4 in BCM numbering.

    To simplify usage, tools like pinout.xyz provide detailed diagrams of the pin layout.
