buzzer circuit


Posted on Feb 7, 2014

This is a project of a 555 buzzer circuit. NE555 is a timer IC comes in 8 pin dip package, it performs wide variety of tasks in electronic circuits. The circuit mentioned below will produce a buzzer sound when 9 volt power will be applied. The frequency of sound can be changed with the help of 1K variable resistor and changing the value of 15K res
