Smart Blind Stick Using Arduino Uno

An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.

Smart blind stick using arduino uno.

However if you are curious to know how the code works read further. An ultrasonic sensor hcsr04. The smart stick is built on arduino pro mini. 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.

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. Arduino program for smart blind stick. The stick uses ultrasonic sensors for obstacle detection. 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.

As we can see an arduino nano is used to control all the sensors. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. The ldr is connected with a resistor of value 10k to form a potential divider and the difference in. Presented here is a smart stick using arduino uno.

This smart stick can help blind people walk on the street safely without any help. The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. 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. Once we are ready with our hardware we can connect the arduino to our computer and start programming.

The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. Smart blind stick project using arduino and sensors. Person suffering from night blindness cataracts glaucoma albinism or injury. The technology can indeed neutralize human disability.

The complete code used for this page can be found at the bottom of this page you can upload it directly to your arduino board.
