Smart Blind Stick Using Arduino Circuit Diagram

This arduino smart blind stick project requires two separate circuits.

Smart blind stick using arduino circuit diagram.

Using this smart blind stick a visually impaired person can walk without anyone s help. The whole project has been designed on eagle. Ultrasonic gnd to arduino gnd. One is the main circuit which will be mounted on the blind man s stick.

That was the simplest way to make a smart stick for blind people using arduino. Ultrasonic blind walking stick using arduino circuit diagram. The cane can automatically detect an obstacle and give the user a feedback response by vibrating the walking stick and giving a warning sound. Prototype of arduino based smart blind stick there are two circuits in the project remote switch and the smart stick.

One is the main circuit which will be mounted on the blind man s stick. The circuit diagram and pcb design are given below. It is pretty easy does not have complicated wiring. The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic.

Read arduino isp log. Here i will explain by parts. You can see the wiring diagram from the above image. A buzzer is connected between d9 pin of arduino and gnd pin.

The same circuit prototype can be made using a breadboard or zero pcb. 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. To design blind walking stick using arduino ultrasonic sensor hc sr04 make the following connections as shown in the connection diagram below. The other is a small remote rf transmitter circuit which will be used to locate the main circuit.

Using this arduino smart cane a visually impaired person can walk without anyone s help. It cost me just 10 to make one. Blind walking stick arduino ultrasonic sensor. The main board s circuit diagram is shown below.

Now it is time for wiring the arduino. Ultrasonic vcc to arduino 5v. Smart blind stick project using arduino and sensors. This arduino smart blind stick project requires two separate circuits.
