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.

That was the simplest way to make a smart stick for blind people using arduino. The same circuit prototype can be made using a breadboard or zero pcb. The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic. You can see the wiring diagram from the above image.

The circuit diagram and pcb design are given below. The other is a small remote rf transmitter circuit which will be used to locate the main circuit. Now it is time for wiring the arduino. The main board s circuit diagram is shown below.

Ultrasonic gnd to arduino gnd. Ultrasonic blind walking stick using arduino circuit diagram. It cost me just 10 to make one. Blind walking stick arduino ultrasonic sensor.

The cane can automatically detect an obstacle and give the user a feedback response by vibrating the walking stick and giving a warning sound. Smart blind stick project using arduino and sensors. Using this smart blind stick a visually impaired person can walk without anyone s help. Circuit diagram picture courtesy.

I used an ultrasonic sensor with an arduino for detecting the obstacles. It is pretty easy does not have complicated wiring. Prototype of arduino based smart blind stick there are two circuits in the project remote switch and the smart stick. A buzzer is connected between d9 pin of arduino and gnd pin.

This arduino smart blind stick project requires two separate circuits. To design blind walking stick using arduino ultrasonic sensor hc sr04 make the following connections as shown in the connection diagram below. One is the main circuit which will be mounted on the blind man s stick. Ultrasonic vcc to arduino 5v.

Here i will explain by parts. Read arduino isp log. 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. One is the main circuit which will be mounted on the blind man s stick.
