Touch Screen and GSM based fastest messaging system

Description

In the kit touch screen and GSM-based fastest messaging system in any organization or company; there is information that keeps flowing among the people of the organization. For this reason, the people are required to be called by some authority frequently. Here we have designed a one-touch fast messaging system to solve these problems. There is a touch screen from which a person can select a user from the group and can select the message. After the selections, he can send the message to the relevant person by pressing ok. It can be used for fast calling systems also. The user has to neither type a message or the number and hence it works faster.

In the kit touch screen and GSM-based fastest messaging system, the touch screen is a four-wire resistive touch screen that is interfaced with analog pins of the microcontroller. The microcontroller reads the coordinate of touch by measuring the change in voltage on the pins of the controller. The GSM modem is connected with the microcontroller and works on the UART port. There is a dot-matrix LCD connected with the microcontroller for the display of the message and the number. The logo behind the touch screen assists the user on the touch screen. The system requires a 12V 1A of power supply.
