SCHOOL PURPOSE AMPLIFIER
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
The world over the decade's has made considerable advancement in automation ,automation is employed in home ,industries, commercial & educational sector. In this work ,a microcontroller base automatic school bell timer amplifier is design.When school or collage start then amplifier is ON & play's the National anthem after this the amplifier off automatically & after every period the buzzer play through the speaker. When the last lecture is finished then the national song ( "Vandemataram") is play through the amplifier. Then operation is done without any human intervention so we get high degree of accuracy. This kit contains eight different timing interval in only one ic. The timing modes & delay ranges are selected by on board push on switch's. Simply select the time delay you want . Timer can display the real time clock in 24 hour mode.
