WebThe GPIO pins allow the Raspberry Pi to control and monitor the outside world by being connected to electronic circuits. The Pi is able to control LEDs, turning them on or off, run motors, and many other things. It’s also able to detect whether a switch has been pressed, the temperature, and light. We refer to this as physical computing. WebJun 4, 2024 · Multiplexed means the pin can serve multiple purposes. Common combinations are GPIO and Address. On some chips, the High Order address lines can be multiplexed as GPIO, so if you don't need the address range, you can have more I/O pins. – Thomas Matthews Jun 4, 2024 at 16:49 graphic bobs
