automatic college/school bell timer :

this product takes over the task of ringing of the bell in colleges. It replaces the manual switching of the bell in the college. It has an inbuilt real time clock (ds1307)which tracks over the real time. When this time equals to the bell ringing time, then the relay for the bell is switched on. The bell ringing time can be edited at any time, so that it can be used at normal class timings as well as exam times. The real time clock is displayed on lcd display. The pic microcontroller is used to control all the functions, it get the time through the keypad and store it in its memory. And when the real time and bell time get equal then the bell is switched on for a predetermined time.
