Abstract

Thesis "Voice Actuated Light Switch" is a project where ,,:histle sound (high frequency voice) is used to actuate the light. Light Emitting Diode (LED) is used in this project as an indicator. The LED will light up when the circuit is closed and vice versa when the circuit is open. The whistle sound will captured by a microphone and then this sound is converted to electrical signal for actuating the LED. The same sound is used to de-activate the light. In other words, whistle sound is replacing the switch to on and off the LED. Besides the schematic diagram, detail explanation on the theoretical part of each electrical. components used are also included in this thesis. Signal processing in major components are also discussed to know how sound is converted to electrical signal and to know how this signal affect the overall cireuit. This thesis also describe the advantages and disadvantages and also problems enc~)Untered during the developing of this project.
