The stick uses ultrasonic sensors for obstacle detection.
Smart blind stick using arduino pdf.
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.
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.
The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator.
Once we are ready with our hardware we can connect the arduino to our computer and start programming.
