GPIO

Embark on a journey into the world of General Purpose Input/Output (GPIO), a crucial aspect of hardware programming and embedded systems development. GPIO enables the interaction between microcontrollers, like the popular Raspberry Pi, and external devices, empowering you to control and manipulate the physical world through digital signals.

Understanding GPIO

GPIO ports act as a bridge between the digital domain of microcontrollers and the analog realm of external devices. They allow microcontrollers to send and receive electrical signals, enabling the control of lights, motors, and other electronic components. GPIO pins can be configured as inputs, outputs, or both, providing versatility in hardware interactions.

The Raspberry Pi, a versatile single-board computer, is a popular platform for learning and experimenting with GPIO. Its wealth of GPIO pins and easy-to-use programming language, Python, make it an ideal choice for beginners and hobbyists alike.
