Smart blind walking stick / Nur Diyanah Rosli ... [et al.]

This modern blind stick has several features that can help the blind to navigate routes and detect an obstacle. This research project's main purpose is to construct an Arduino microcontroller hardware that can corroborate a blind person to detect obstacles in front of him/her instantly. The hardware consists of an Arduino microcontroller incorporated with an ultrasonic sensor, water sensor, piezo buzzer and other additional equipment. The casing box and water sensor slot were made out of PLA by using 3D printing process and are used to protect the Arduino board and breadboard while allowing easy accessibility. Furthermore, the water sensor slot helps to keep the sensor's pins from getting wet and causing it to malfunction. Aside from that, this section strengthens the stick's structure at the end. The final result for this project is that all the sensors in the smart blind walking stick can operate according to their functions.
