Abstract: Brain Computer Interface (BCI) is the direct connection between the computers and human brain. The BCI reads the waves for particular Attention level produced from the brain at different locations in the human head, translates these signals into actions. This system is especially useful for disabled people or people with no reliable muscular control over their body parts to interact with surrounded peripherals. The system involves two parts: an EEG sensor circuit or Mind wave headset and an Arduino board. The brain wave sensor will sense brain signals at particular attention level and this brain signals are transferred to the Arduino using HC-05 Bluetooth module and it will convert the data into packets and transmit through Bluetooth. Then the control command will transmitted to the relay circuit and appliances work. With these entire connection system can control any home appliances through brain signals, which connected to the relay circuit.

Keywords: Brain Computer Interface (BCI), Attention level Sensor, Head Set, EEG Signal, Bluetooth Module, Arduino board.
