We design a device for helping a blind person. By using this device, the blind doesn't need to use stick or dog for helping him or her. The device will help the blind person for figuring the obstacle in front of him or her. We use microcontroller, an ultrasonic sensor as an input, and an electromechanical buzzer as an output. The device is proved accurate when we tried it for the distance 150 centimeters, 100 centimeters, and 50 centimeters between the user and the object.
