IOT BASED AUTOMATIC WIRELESS SIREN USING ARDUINO CONTROLLER

The main objective of this project is to implement an Automatic college siren system using an Arduino. In this Arduino based college siren circuit, we used three major components which are IC RTCDS3231,Arduino Uno Board, and 16x2 LCD modules. Here, Arduino is used for reading time from ds3231 and display it on 16x2 LCD. DS3231 sends time/date using 2 lines to arduino. A siren is also used for alarm indication, which beeps when alarm is activated, simultaneously voice module will read out the data displayed on the LCD module. Here, the code is designed in a way so the bell will be activated for every 50 minutes as per the college schedule. The siren will be ringing for 50 seconds from the instant it is activated and simultaneously LCD screen will display the completion of a particular session, which indicates the students and faculty about the completion of a particular session and simultaneously the voice module will also read out the data which is being displayed on the L
