Oct 15, 2023 · Since I often use the RaspberryPi board for some non critical automation that requires more than the computational power of an AVR or where having a full blown operating system is just more convenient I also often want to use the GPIO pins as on any embedded device. Is your question about GPIO addresses or C coding? It is also pointed out in the comments that the register base address changed for Pi 2 and Pi 3. Controlling a garage door is simple: connect the GPIO output pin to one side of a relay's coil, connect the 5 volt output of the Pi to the other side of the relay's coil, and connect wires from your garage's wall console to the relay's common and "normally closed" ports.
