Walking stick assistant for visually impaired people with IoT / Hanis Syahirah Khairul Azlan

Visually impaired person have difficulty to interact and feel their environment since they have little contact with surroundings which they intend to move to anywhere busy place. These problems of visually challenged people can be addressed with the technology given by using IoT hardware and link with each other by using application software on smartphone. This report aims to design a Smart Walking Stick by using Arduino D1 WEMOS Microcontroller with a combination of Blynk application. These project explains that smart walking stick also helps to guide visually people without burdening other people too. So, this project divided into four parts such as electronic component, electrical device, computer software and a hardware mechanical design. Since Arduino D1 WEMOS is used as microcontroller board, ultrasonic sensor has been used to detect any obstacles, push button as an emergency button and temperature humidity to read surrounding temperature and alert the user. For the output, light emitting diode (LED) are used as a signal to show and alert the user’s guardian if there is an emergency incident occurs, buzzer to notify the blind people if there is an object appears in front of them and LCD to display the temperature of surrounding. So, the results will be displayed on smartphone of the user by using Blynk application. The model discussed here is convenient and affordable smart walking stick equipped with various of IoT sensors, this model will help the visually challenged people to become more alert and also monitor whereabouts of the user to concerned people using tracker location (Blynk application) so that the safety of the users are guaranteed. The complete model is developed and the performance is reported
