Traffic Controller With RTC
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.
