Abstract:
Main purpose for this Project is to design an electronic circuit which will be used to prevent bag snatching.
Ant bag snatching alarm circuit used in bag or suitcase to prevent it from snatching, this is simple alarm circuit kept in a bag or suitcase that’s sound a loud alarm, simulating a Police horn. This will draw the attention to other people and snatcher can be caught. So when the snatcher tries to snatch the bag, the plug detaches from the unit socket to activate the alarm.
The heart of this entire circuit project is operation amplifier that configured as Comparator, 555Timer-IC which used as monostable multivibrator and for the audio section it used Sound generator with in built oscillator. After sound is amplified it fed to the transducer (loudspeaker) for output
