In this competitive world and busy schedule human can’t spare more time to perform daily activities manually. It is very easy to control devices through PC instead of controlling devices manually. To communicate any device to pc needs HyperTerminal which is understand only by technical people. But it is better to have any extra communication in between PC and device. So that we have tool called as “front ends”. These front ends are very good and which are very easy. Non technical people easily interact with device from PC easily. These front end tools are designed by C# .net application. Communication has good visibility and good interaction in front ends (These front ends may vary from project to project). In this project microcontroller is connected to GSM modem and PC using a line driver IC max232 for serial communication. PC has C# .net application and it can convert text to voice. Microcontroller gets data or message from GSM modem and sends to application through serial communication. Application always opens the com port and read data on com port. This project is helpful in data loggers, industrial security systems and industrial parameters announcement…etc., user can monitor messages from remote place also. We can implement any type voice announcement system through this project. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
