Abstract: The goal of this project is to measure electric activity in the brain due to firing of the neurons, parse wave to obtain attention and meditation level of brain and using it to move a Wheel Chair. The interactions between neurons create an electric discharge which cannot be measured using current technology. There are different techniques available to detect electric activity in brain. One technique is Electroencephalography (EEG). EEG measures voltage fluctuation along the scalp that results from the interaction between the neurons in the brain. These voltage fluctuations are processed and output to a microcontroller by the EEG sensor. The data packets obtained from the EEG sensor are stored in microcontroller. The attention and meditation levels are obtained from the processed data. These levels are used to control the direction and motion of the Wheel Chair.
