Abstract

This project is started with an objective to help the visually impaired people from continuing their daily lives. The normally used cane is found to have many limitations, which has caused many problems including the inability of detecting head-level obstacles and water on the floor. Hence, this project is aimed to improve and transform the traditional white cane into a modern smart cane which is fully equipped with useful devices (ultrasonic sensor and water sensor). Plenty of researches have been carried out to understand the application of the usage of Arduino Uno and different sensors installed on the smart cane. In this project, the various kinds of hardware and software are being utilized. Many components will be used in this project, including ultrasonic sensor, water sensor, buzzer, vibration motor, and Arduino Uno which form the hardware part of the project while Arduino IDE is used as the software part of the program. After all the required components have been collected, the project is started immediately with the testing of each component. Then, several actions are to be carried out to test the performance of each of the special function of the smart cane, including detecting obstacles and water in front of the users. The results of testing will be tabulated and shown in graphs and tables. Then, they are compared and improved to find out the limitation of the smart cane as well as the limitation of the project. After the smart cane is made, recommendations will be given to enhance more experiment made in future to improve the smart cane based on the limitation.
