A harsh fact that half million of children go blind each year shows that blindness is one of the significant problems that require a comprehensive care. Some people might consider blindness as a sickness which blind people should be pitied and disable to perform by themselves. In other way it might leads blind people to a "life of dependence" which means that they can not do the activities as normal people can do without assist from others. This could be one of the factors that increase the unemployment rate among a blind community. Blind Echolocation is designed to meet the need of an effective way to assist the blind people to live independently with least help from other people. Although a blind person has a visually impaired but he or she still can hear an echoic sound to determine the direction and distance of the obstacles. Therefore the idea of this project is to make use of Ultrasonic Sensor to produce a device which can be a useful navigation aid for the blinds. The goal of the device is to indicate the obstacles in an environment by triggering the alarm.
