Smart Blind Stick Using Arduino Circuit Diagram

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

Smart blind stick using arduino circuit diagram.

You can see the wiring diagram from the above image. Now it is time for wiring the arduino. Using this arduino smart cane a visually impaired person can walk without anyone s help. The circuit diagram and pcb design are given below.

I used an ultrasonic sensor with an arduino for detecting the obstacles. This arduino smart blind stick project requires two separate circuits. The whole project has been designed on eagle. The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic.

The other is a small remote rf transmitter circuit which will be used to locate the main circuit. One is the main circuit which will be mounted on the blind man s stick. The main board s circuit diagram is shown below. Follow all of the steps mentioned above and after successful testing of the project look for a disable person and offer him this project to make his her life easier.

That was the simplest way to make a smart stick for blind people using arduino. Blind walking stick arduino ultrasonic sensor. Here i will explain by parts. Prototype of arduino based smart blind stick there are two circuits in the project remote switch and the smart stick.

The other is a small remote rf transmitter circuit which will be used to locate the main circuit. It cost me just 10 to make one. It is pretty easy does not have complicated wiring. This arduino smart blind stick project requires two separate circuits.

Circuit diagram picture courtesy. A buzzer is connected between d9 pin of arduino and gnd pin. Smart blind stick project using arduino and sensors. Ultrasonic gnd to arduino gnd.

The same circuit prototype can be made using a breadboard or zero pcb. Read arduino isp log. Using this smart blind stick a visually impaired person can walk without anyone s help. Ultrasonic blind walking stick using arduino circuit diagram.
