Smart Blind Stick Using Arduino Circuit Diagram

Using this arduino smart cane a visually impaired person can walk without anyone s help.
Smart blind stick using arduino circuit diagram. Prototype of arduino based smart blind stick there are two circuits in the project remote switch and the smart stick. That was the simplest way to make a smart stick for blind people using arduino. It cost me just 10 to make one. This arduino smart blind stick project requires two separate circuits.
The main board s circuit diagram is shown below. Ultrasonic vcc to arduino 5v. The whole project has been designed on eagle. The same circuit prototype can be made using a breadboard or zero pcb.
I used an ultrasonic sensor with an arduino for detecting the obstacles. 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. This arduino smart blind stick project requires two separate circuits. Now it is time for wiring the arduino.
Ultrasonic gnd to arduino gnd. You can see the wiring diagram from the above image. Here i will explain by parts. The circuit diagram and pcb design are given below.
Circuit diagram picture courtesy. Using this smart blind stick a visually impaired person can walk without anyone s help. One is the main circuit which will be mounted on the blind man s stick. A buzzer is connected between d9 pin of arduino and gnd pin.
To design blind walking stick using arduino ultrasonic sensor hc sr04 make the following connections as shown in the connection diagram below. The cane can automatically detect an obstacle and give the user a feedback response by vibrating the walking stick and giving a warning sound. The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic. Smart blind stick project using arduino and sensors.
Read arduino isp log. The other is a small remote rf transmitter circuit which will be used to locate the main circuit. It is pretty easy does not have complicated wiring. One is the main circuit which will be mounted on the blind man s stick.
