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