Smart Blind Stick Using Arduino Code

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.

Smart blind stick using arduino 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. Code file is given in the link just download this file and upload to arduino. Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st. However if you are curious to know how the code works read further.

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. This is a arduino code which you can run on arduino ide. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.

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. This smart stick can help blind people walk on the street safely without any help. The stick uses ultrasonic sensors for obstacle detection. Once we are ready with our hardware we can connect the arduino to our computer and start programming.
