Arduino Based Blind Stick With GPS And GSM
step by step guide how you make your own blind stick with GPS And GSM
Introduction
Hi Friends In this Blog You Learn All About Blind Stick Using GPS And GSM modules. I Will Explain All The Things In Detail about How the Project Will Work.
- The Amin Problem Of Blind People Is how to navigate their way to whenever they want to go. that’s such people need to blind Stick.to find out the correct path.
- The blind people put the ultrasonic Sensor in a cap and then move. The ultrasonic sensor put both sides front and back side, if the front ultrasonic sensor senses the obstacle the buzzer beeps which means they inform the Blind People is an obstacle in your front. if blind people move backside and back side ultrasonic sensor sense the obstacle that’s the time buzzer is beep in a different sound. then blind people listen to the sound and know the buzzer beep sound is easy to understand where is come obstacle.
- Now the blind people carry the stick I just put the water sensor on the downside of the stick. if stick goo in water they inform the blind people is some water is a downside and is easily understood. if blind people facing some problem then just press the push button that’s the time GSM Send the text message to the parent’s mobile number Or Police Station With a Proper GPS Location.
Bill Of Materials
Here I put All the Component List Which I Used In this Project
S.N | Components | Quanitity | Link To Buy |
1 | Arduino Nano | 1 | |
2 | GSM Sim800l Module | 1 | |
3 | LM2596 Step Down Conveter | 1 | |
4 | GPS Neo-6m | 1 | |
5 | HC-SR 04 Ultersonic Sensor | 1 | |
6 | Water Sensor | 1 | |
7 | Push Button | 1 | |
8 | Buzzer | 1 | |
9 | Zero PCB | 1 |
Hardware Part
In This Project, I used the Arduino nano microcontroller Board Because is Small And is providing the Soo many pins.
SIM800l Gsm module size is Also Small And Is Required 3.7 volts only
- RX Pin-Connected To The D2 Pin
- Tx Pin-Connected To The D3 Pin
- LM2596 is a step-down converter that converts the 9v or 12v Dc Supply To 3.7 volts and GSM sim800l is required for the 3.7-volt Supply.
- GPS Neo-6m Module This is also in small size and they work on the 5v DC Supply
- RX Pin-Connected To The D10 Pin
- Tx Pin-Connected To The D11 Pin
- HC-sr04 Ultrasonic Sensor In this project I used 2 ultrasonic sensors that work on the 5v DC Supply
1. Ultrasonic Sensor
- Vcc 5v
- Echo A0 Pin
- Trig A1 Pin
- Gnd Gnd
2. Ultrasonic Sensor
- Vcc 5v
- Echo A2 Pin
- Trig A3 Pin
- Gnd Gnd
The water Sensor also Work On 5v if water touches the sensor that’s time sensor signal is High
- VCC 5v
- Signal A4
- Gnd Gnd
- Push Button they Connected To The Pin Number D6
- The buzzer will be connected to the PIN D8
- In this Project we Used The 4×4 Zero Pcb I soldered All The Components In The zero PCB.
