The aim of Touch Screen Based Nurse/Attendant Calling System For Physically Impaired project is to design and construction of a module used for patient who are unable to move . it control the buzzer/light indication by a simple touch through touch screen. The project was divided into three phases. The First phase is to demonstrate the application of touch screen. The second phase of the project attempts controlling and display data on Graphic lcd and the third phase of the project is to control the devices(buzzer/lamp).
A typical graphics LCD system is shown in Figure 1. The system consists of a microcontroller, a LCD controller (digital-control logic, optional graphic accelerator, image buffer, gate driver), and a LCD glass.
Devices used in this project.
