A standalone apache server is running on Rpi3, and a PHP webpage is used to control the GPIOs, a mysql database intigration is also there to ensure system memory like timers. By using tunnelling the local server is also available over the air on a specific website of your choice. All 26 GPIO's can be controlled individually spontaneously or by applying timers which can be used say as for a home automation, like heater, AC, Lights and fan control. IP camera is optional. Can be merged with the same application with recording facility.
Right now I'm simulating the switching with LED on off. Projet is ready for a demo. It is mainly a programming project using the possibilities of Raspberry Pi board.
