Abstract:

The world over the decades has made considerable advancement in automation; it is employed in homes, industries, commercial and educational sectors. In present work, a solar power-operated microcontroller-based automatic college bell is designed and developed. For the harmonic tuning, converted normal college bell into automatic college bell and powered by solar PV system with battery backup. It uses electrical coil for generating the EMF for striking the clapper on the edge of a bell for making sound. It uses the Real Time Clock (DS1307) which tracks the real time. The microcontroller (ATMEGA 328p) is used to control all the functions; it gets the time through the keypad and stores it in its memory. When programmed time equals the real time then the bell is switched on via a relay for a predetermined time. The bell ringing time can be edited at any time so that it can be reused again and again at normal class timings as well as at exam times. The advantage of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence takes over the manual task of switching on/off the college bell with respect to time. It works on onetime time setup.
