before that guys, let me tell u what our project was all about.. this project is called Emergency Siren Simulator with Light Indicator. So basically its for emergency alarm.. whenever we press the button and hold to trigger the alarm, the alarm will wale up until u let go off the button to make it wale down. This is basically because of the frequency of oscillation climbs to a peak and when the button is released, the frequency descends due to the rising and falling voltage on the 22 microFarad capacitor. So, this is some of the details of our project. Well here goes the photos.. =D enjoy..
