This is a project to create a travel assistance for the blind. The objective is to facilitate blind using the Arduino microcontroller boards to control play, says Thailand through language, measure the distance between the objects by value. reflected waves from the back of the alarm circuit the distance of the object (Ultrasonic Sensor) process to detect and sound an alarm blind by sending an audio signal. How to perform a clean startup from the study data related to the project. Design and construction of cycle include: Control circuit and a circuit measured the distance between the objects. Equipment procurement, and then save the sound, and then write the driver and processing in order to obtain a set of conditions, and then perform a test result from the test machine in travel assistance for the blind. Can follow the defined boundaries is the measure of distance between the objects with the user properly text-to-speech and who closely works with the warning.
