TRAFFIC CONTROLLER WITH RTC

0
238

INTRODUCTION:

The main aim of this project is to operate the traffic lights based on the predefined timings. This system switches on the lights only at preprogrammed timings. As the DS1307 Real Time Clock chip with battery back-up is used, there will be no disturbances for the programmed on/off timings even in power failures.

Three switches are provided for entering the required timings. These switches made this project user friendly. 16X2 LCD display is provided to display the alarm times and current time. DS1307 is interfaced to the microcontroller for real timing performance. A 3V battery can be connected to DS1307 to avoid time disturbances caused by power failures. The user can even change the preprogrammed timings and set the timings according to his requirements.
