dc.description	The name of our final year project is Sound Controller Outlet. This is a project on the design and construction of sound activated switch for low power rated home appliances, which was made has though it were an extension box with two socket outlets that can be controlled independently via clap or any sound at all. It is capable of setting different mode of operation based on the level of sensitivity its users require. The basic idea behind this work is that an electric mic picks up sound from the user of the device, produces a small electric signal which is amplified by a transistor configured in the common emitter mode. The amplified output and the pins of a slider switch which was connected via resistor to 5V regulated power supply served as an input to a micro controller (Atmega8). The analogue to digital converter (ADC) and the timer, which are pheripherals of the micro controller were used to control the input via code to give an output as appropriate which were sent to a relay via a relay driver. After construction, several test was carried out in the 3 modes of operation (high, low and away), its outcome showed that the device made was intelligent enough to select which outlet the sound made was to control while several low power rated home appliances such as television (TV) and bed lamp were plugged to it.	en_US
