Combining multiple assistive functions into one handheld device.

The project explores how embedded systems can be integrated into an everyday mobility aid to provide additional safety and convenience features.

An Arduino Nano acts as the main controller, communicating with sensors, a display, audio output, buttons, and other components integrated into the cane.

An Arduino-based system combining sensors, displays, and peripheral modules.

Sensors collect information while the Arduino processes it and provides feedback.

The MPU6050 provides motion information that can be used for movement-related functions such as step counting.

The DS3231 real-time clock provides accurate time information for reminder functions.

The LDR detects surrounding light levels, allowing the system to respond to darker environments with an LED.

The OLED provides visual information to the user, while the DFPlayer Mini can provide audio feedback or reminder sounds.

Hardware integration was the core challenge of the project.

The project involves integrating multiple modules with the Arduino Nano while managing their communication, power requirements, and software logic.

Components communicate through interfaces such as I²C, while buttons and other modules are connected through dedicated digital and analog inputs.

From individual modules to an integrated assistive system.

The Smart Assistive Cane is a hands-on embedded systems project focused on combining multiple hardware components into a functional prototype.
