Room Calling Indicator Using Arduino

As generally you see in hospital or hotels when any user will press button from his room then at counter related room light will turn on & one buzzer will produce beep for notification for receptionist. As receptionist will serve service in that room that by pressing push button he can turn off that room light.

For demo we have provide 5 buttons for different room’s & 5 led, 5 Button’s & one buzzer at receptionist counter. User have to increase button wire length if he wants. Here we have 2 devices in this project, one is TX & another RX.

TX Unit:

5 button’s for different room’s are in this device. They are attached with one Arduino with HC05 blue tooth module.

RX Unit:

5 led, 5 Button’s & one buzzer  is attached with Arduin0 which is also interfaced with HC05 blue tooth module.
