GPIO Programming
GPIO (General-Purpose Input/Output) programming involves controlling and reading from hardware pins on microcontrollers, single-board computers, or embedded systems to interact with external devices like sensors, LEDs, and motors. It enables developers to write software that manipulates digital signals for tasks such as turning components on/off, reading button presses, or communicating with peripherals. This skill is essential for embedded systems, IoT projects, robotics, and hardware prototyping.
Developers should learn GPIO programming when working on embedded systems, IoT devices, or hardware projects that require direct interaction with physical components, such as in robotics, home automation, or sensor networks. It is crucial for prototyping with platforms like Raspberry Pi, Arduino, or ESP32, where controlling LEDs, reading from buttons, or interfacing with sensors is common. Mastery allows for low-level hardware control, enabling efficient and responsive real-time applications.
