Smart Walking Stick for Visually Impaired MotivationVisually impairment is a factor that greatly reduces the mobility of people. Currently the most widespread and used mean by the visually impaired people are the white stick, however it has limitation. With the latest technology, it is possible to extend the support give to people with visual impairment during their mobility. IntroductionElectronic stick, whose objective is to give users the confidence to move around in unfamiliar environments. n this project, We proposed an idea of designing electronic stick using !ltra"sonic technology.!ltrasonic sensors to trace the obstacle at a specific distance.Block DiagramArduino Arduino Ultra Sonic SensorUltra Sonic Sensor9Volts Power Supply9Volts Power SupplyBuzzerBuzzerCircuit DiagramATMEGA Micro ControllerUltrasonic Sensor !ltrasonic sensors are much more efficient than other obstacle detection sensors. !ltrasonic #ensors relatively inexpensive and also the ultrasound emitters and detectors are portable without the need for complex circuitry. real time assistance and artificial vision along with dedicated obstacle detection system is provided.DistanceObstacles Ultrasonic Sensor PrincipleHC-SR!
