Using joystick to control a micro servo

The project is based on home automation but it does not come under IoT as a disabled person's helper can attach the servo besides the switch of the fan, lights, etc so that the person becomes independent. This is just a prototype and if the reader likes it and if disabled people can use it then I can make the wire of the servo longer and also the joystick can be embedded in the wheelchair of the disabled so that the person who can not walk can use the joystick easily. this was the aim of my project.
