Resumen
The development of electronic technology, especially in the field of microcontroller very rapidly. Has a lot of application and utilization of the microcontroller that are useful in everyday life as well as in research in the laboratory. In the health sector, influential electronic technology in the manufacture of medical devices. Therefore, the authors make Sticks help the visually impaired to take advantage of technological advances.In this scheme the ultrasonic sensor is used to detect an obstacle or object,in detecting an obstacle, there are two conditions that obstacle distance near and far distances hitch, hitch the closest distance of less than 50 cm and the distance is much hindrance between 50 cm to 150 cm. Arduino microcontroller will then process the data detection results from the sensor, if there is an obstacle or object and then Buzzer DC motor vibrator will be lit as a warning sign.Keywords: Arduino microcontroller, SRF04 Ultrasonic Sensors
