One is the main circuit which will be mounted on the blind man s stick.

Smart blind stick using arduino report.

Smart blind stick using arduino ppt 32. The other is a small remote rf transmitter circuit which will be used to locate the main circuit. The same circuit prototype can be made using a breadboard or zero pcb. Ultrasonic blind walking stick using arduino circuit diagram.

Smart blind stick using arduino pdf 33. Smart blind stick using arduino code 34. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick all the feedbacks will be given to the blind man through a buzzer.

This arduino smart blind stick project requires two separate circuits. 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 circuit diagram and pcb design are given below. Using this smart blind stick a visually impaired person can walk without anyone s 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. The stick uses ultrasonic sensors for obstacle detection. Read arduino isp log. A buzzer is connected between d9 pin of arduino and gnd pin.

The whole project has been designed on eagle. Smart blind stick project using arduino and sensors. Through this the blind person can aware about the obstacles in front of him. Presented here is a smart stick using arduino uno.
