GPIO

GPIO, or General Purpose Input/Output, is a flexible interface on electronic devices like microcontrollers or single-board computers (e.g., Raspberry Pi). It allows these devices to connect with and control or receive signals from other electronic components such as sensors, switches, LEDs, or motors. Think of GPIO pins as versatile connection points that can be programmatically configured to read input signals or send out output signals. This makes GPIO essential for customizing how devices interact with the physical world, enabling projects like home automation, robotics, and data collection.
