The blindstick with ultrasonic sensor is a device designed to assist blind people in navigating their surroundings. The device uses an ultrasonic sensor, a buzzer, and a vibrating motor to provide audio and tactile feedback to the user.
- Detects obstacles in the user's path using an ultrasonic sensor
- Generates different beeps based on the distance of the obstacle from the user
- Provides tactile feedback through a vibrating motor when the obstacle is very close
- Helps blind individuals become more independent and improve their quality of life
- Arduino UNO
- Ultrasonic sensor (HC-SR04)
- Buzzer
- Vibrating motor
- Breadboard
- Jumper wires
