SUMMARY OF PROJECTS
Projects are implemented with the aim of researching and manufacturing the navigation device for the blind. Besides, researchers learn about KIT STM32F4 Discovery and principle of operation and applications of two important hardware devices used in the project is the ultrasonic sensor HC - SR04 and Bluetooth module HC - 05.
The request to implement the project basically achieved. Products were given the test and has recorded positive results, such as:
• Manufacturing is a navigation device for the visually impaired to use ultrasonic sensor, Bluetooth module HC - 05 and a vibration motor.
• Calculate the distance from the ultrasonic sensor to the obstacle with high accuracy.
• Develop a software transmit / receive data between Bluetooth modules communicate via USART details. Allow from using ultrasonic sensors to measure the distance the user can get the vibration signals on wrist with different vibration modes depending on the distance segment.
• Analysis and Design for Facilities was to bring the convenience and comfort to users.
