Smart Blind Stick Using Arduino Uno

As we can see an arduino nano is used to control all the sensors.

Smart blind stick using arduino uno.

The smart stick is built on arduino pro mini. An ultrasonic sensor hcsr04. Person suffering from night blindness cataracts glaucoma albinism or injury. The stick uses ultrasonic sensors for obstacle detection.

The ldr is connected with a resistor of value 10k to form a potential divider and the difference in. A third eye for the visually impared people. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. Hi guys how to make a smart blind stick using arduino uno and ultra sonic sensor.

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. Once we are ready with our hardware we can connect the arduino to our computer and start programming. Presented here is a smart stick using arduino uno. This smart stick can help blind people walk on the street safely without any help.

An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to. However if you are curious to know how the code works read further. 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.

The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. 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. Arduino program for smart blind stick.

Using this smart blind stick a visually impaired person can walk without anyone s help.
