DESIGN AND CONSTRUCTION OF SOUND OR CLAP ACTIVATED ALARM
This project is titled design and construction of sound detector with alarm. sound detector with alarm is an electrical device that allows appliances/alarm and products to be turned on and off from sound. The most important feature of the sound detector with alarm is its small microphone. The microphone detects sound, such as laughs, slamming doors, and claps of hands. The sound is changed into electrical waves. The electrical waves are magnified by a transistor. The transistor feeds the amplified sound to a flip-flop circuit. The flip-flop reverses the output and feeds another amplified circuit. The amplified circuit is connected to a relay contact which acts as a mechanical switch. The relay can be connected to an electric device to make the device turn on and off by the clap of hands or a similar sound.
