Introduction:
In recent years, wearable technology has become increasingly popular, providing innovative solutions for health monitoring, navigation, and assistance for differently-abled individuals. One such innovation is Smart Shoes Using Arduino, a project designed to enhance safety, mobility, and awareness for users, especially the visually impaired and elderly.
This system integrates an Arduino microcontroller with sensors such as an ultrasonic sensor and an IR sensor or accelerometer to create a responsive and intelligent wearable device. The ultrasonic sensor detects obstacles in the user's path and alerts them through a buzzer, ensuring safe navigation. Simultaneously, a step-counting mechanism using an IR sensor or accelerometer provides real-time activity tracking, helping users monitor their movement.
By embedding these components within a shoe, the system becomes discreet and portable, offering hands-free functionality. The Arduino processes real-time data from the sensors, and the entire system is powered by a lightweight battery. The simplicity and cost-effectiveness of the design make it a viable solution for personal safety and fitness tracking in both urban and rural environments.
This project not only demonstrates the practical application of microcontrollers and sensor technology but also addresses real-world problems through innovation and engineering.

Working Principle:
-
The ultrasonic sensor detects obstacles within a predefined range.
-
If an obstacle is detected, the buzzer alerts the user with a sound.
-
An IR sensor or accelerometer counts the number of steps taken.
-
All data processing is handled by the Arduino, which is powered by a compact battery.
-
The system can be turned ON or OFF using a small switch embedded in the shoe.
Applications:
-
Assistive aid for visually impaired people
-
Wearable fitness tracking for step count
-
Fall detection and alert systems (with upgrades)
