Smart Blind Stick Using Arduino Code

The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator.

Smart blind stick using arduino code.

Smart blind stick project using arduino and sensors. The ldr is connected with a resistor of value 10k to form a potential divider and the difference in. Once we are ready with our hardware we can connect the arduino to our computer and start programming. This is a arduino code which you can run on arduino ide.

As we can see an arduino nano is used to control all the sensors. Using this smart blind stick a visually impaired person can walk without anyone s help. 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 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.

Arduino program for smart blind stick. Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st. The smart stick is built on arduino pro mini. Code file is given in the link just download this file and upload to arduino.

Ultrasonic blind walking stick program code. By this the person using the blind stick will be able to know is there any obstacle on his way so that he she will be alert. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. Presented here is a smart stick using arduino uno.

Through this the blind person can aware about the obstacles in front of him. Person suffering from night blindness cataracts glaucoma albinism or injury. 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 stick uses ultrasonic sensors for obstacle detection.

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