What is GPIO?

GPIO (General Purpose Input/Output) is a flexible interface used in embedded systems. It allows microcontrollers and other integrated circuits to interact with external electronic circuits. GPIO pins can be configured as either input pins (reading signals from sensors, switches, etc.) or output pins (controlling LEDs, motors, etc.). They are commonly used for simple tasks such as reading button presses, controlling indicator lights, and interfacing with basic sensors.
