Sound indicators as safety of motorcycle

Abstract

Motorbikes are popular of transportation with high usage rates. Safeguarding motorbikes are a necessity for users to provide security. Researchers offer motorcycle safety using sound indicators. The working principle of motorcycle safety offered, is after the main key, or contact is in position and the Mic sound indicator is blown, amplifier circuit works to drive the relay driver that connects the CDI unit. The motorcycle safety circuit system will live and if there is no blow, the motorcycle safety circuit will not function. Research on the motorcycle safety circuit can be used to input indicator sound. Components needed include Mic condenser, driver relay circuit, power supply. Measurement of the relay driver circuit and condenser mic aims to find out which circuit can work as planned. The measurement results obtained testing the motorcycle safety circuit with the following explanation: When the sound indicator and driver get a touch simultaneously, which gives a signal that the signal from the sound indicator is connected to the amplifier driver, so that the signal is detected, will provide input to the relay (on) and CDI unit when the motorcycle will work. With an indication the LED will turn on.
