The smart walking stick is a very interesting project and ideal for beginners. The main aim of this stick is to alert the visually impaired about an obstacle in his way. Whenever the sensor detects any object in a range of 60 cm it triggers the buzzer.

This project can also be used as a distance finder. (by using serial monitor)

Step 1: Things Required:

  1. Any kind of walking stick
  2. Ultrasonic sensor
  3. Buzzer
  4. Arduino (I am using Leonardo)
  5. Laptop or a computer with Arduino software.
  6. Battery pack or power bank (to power Arduino)
  7. Few jumper wires
  8. Tape

Step 2: Mounting the Components

Mount all the components as shown in the pictures.

Step 3: Connections

Ultrasonic Sensor:

Vcc to 5v

Gnd to Gnd

Echo to Pin 11 (of Arduino)

TriggertoPin 10

Buzzer:

Vccto3v or 5v

Gnd to Gnd

I/O toPin 7

<p>i have a question.<br>what if we make a smart stick for visually impaired person but he lost his stick in his room. so now what shall he do to get to know where is his stick placed.<br>please help me on this i am making this and i need it urgent if someone has code of it please do share i shall be very thankful </p>
<p>to locate the stick you need to build a seperated circuit to be used as a locater eg, 555 timmer clap circuit, or an auido ampliphier with 555 timer circuit. </p><p>Baraa AL-DOUSRE</p>
<p>@muhammadH227 i am also doing same project but with many more components.what i feel is you can either go near the stick to trigger the buzzer so that u can find the device , another way is to use a RFID system. dont know how effective it will be.</p>
