Blind and visually impaired individuals face significant challenges while navigating independently. Traditional walking sticks can only detect obstacles after physical contact, often leading to accidents or injuries. This paper presents the design and implementation of a Smart Blind Assistance Stick using Arduino Uno that integrates an ultrasonic sensor, water sensor, buzzer, vibration motor, and a GSM module. The system detects nearby obstacles using ultrasonic waves, identifies water or wet surfaces using a water sensor, and provides real-time audio and vibration alerts. In emergency situations, a push button activates the GSM module to send an SOS SMS to a predefined contact number. The proposed system improves mobility, safety, and confidence for visually impaired users and offers a cost-effective and user-friendly assistive solution.
