This easy safety alarm circuit may also help you safe your bike or scooter. It raises an alarm if somebody tries to drive away your two-wheeler. You simply want to attach the circuit to the automobile’s wheel (ideally entrance wheel) by a skinny versatile wire that may break simply.
Join the bike’s wheel to the circuit with the wire in such a approach that when somebody tries to steal the bike, the wire would break. When that occurs, the speaker within the circuit would generate a machine-gun sound, or another alarming sound, and alert everybody round.
The prototype assembled on a breadboard for testing in EFY Lab is proven in Fig. 1. Circuit diagram of the safety alarm is proven in Fig. 2.
