CLAP SOUND SENSOR BASED MOTOR/FAN CONTROL SCIENCE MODEL KIT
Brief 
The project is a fully assembled and working model.
The Science Model is designed on White Paper which is labeled neatly on a Soft Plywood Base.
This Model includes Clap/Sound Sensor which senses the sound like clap or tap. These signals are amplified using a NPN Transistor. The amplified signal is then fed to a Timer 555 IC which will generate a square pulse at a certain timer frame. For every clap or tap, the motor will turn on for a certain time period and then turns off automatically. The Time sequence is generated using Resistor & Capacitor integrated to the Timer 555 IC.
On board switch is provided to control the entire circuitry.
The model emphasis on the importance of Automating the Motor Control using simple sounds.
