Smart Blind Stick Using Arduino Uno

This smart stick can help blind people walk on the street safely without any help.

Smart blind stick using arduino uno.

An ultrasonic sensor hcsr04. With this in mind let us use the power of arduino and simple sensors to build a blind man s stick that could be a lifesaver for visually impaired persons. The stick uses ultrasonic sensors for obstacle detection. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.

Using this smart blind stick a visually impaired person can walk without anyone s help. However if you are curious to know how the code works read further. A third eye for the visually impared people. An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.

Once we are ready with our hardware we can connect the arduino to our computer and start programming. Person suffering from night blindness cataracts glaucoma albinism or injury. Smart blind stick project using arduino and sensors. The ultrasonic sensor is powered by 5v and the trigger and echo pin is connected to arduino nano pin 3 and 2 as shown above.

Hi guys how to make a smart blind stick using arduino uno and ultra sonic sensor. The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. As we can see an arduino nano is used to control all the sensors.

The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. This arduino board is small enough to install on a regular stick and has buzzer ldr sensor ultrasonic sensor and a water detector sensor interfaced to it. The ldr is connected with a resistor of value 10k to form a potential divider and the difference in. The smart stick is built on arduino pro mini.

The technology can indeed neutralize human disability.
