Smart blind stick using arduino code. The stick uses ultrasonic sensors for obstacle detection. Using this smart blind stick a visually impaired person can walk without anyone s help. Ultrasonic blind walking stick program code. 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 complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. Person suffering from night blindness cataracts glaucoma albinism or injury. Once we are ready with our hardware we can connect the arduino to our computer and start programming. The smart stick is built on arduino pro mini.
However if you are curious to know how the code works read further. 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. Presented here is a smart stick using arduino uno.
Arduino program for smart blind stick. In the code a library is used by the name ultrasonic h this library is not added in arduino by default. 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. Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st.
Through this the blind person can aware about the obstacles in front of him. Smart blind stick project using arduino and sensors. This smart stick can help blind people walk on the street safely without any help. 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.
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. The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.
