Blind Stick with GPS and GSM using ATEGA328 project is design for Blind Person i.e. visually disabled people for improved navigation, so that they can walk and avoid bumping into obstacles. Our project proposed a prototype of blind stick which is integrated with micro controller ATMEGA328, ultrasonic sensors, water sensor, light sensor, GPS and GSM.

There are following function:

  1. Our project has ultrasonic sensors, which alert the person for any obstacles in a way by using ultrasonic sensors which detect obstacles ahead using ultrasonic waves. When these sensors sense obstacles, then it passes signal to the microcontroller for further process. After then microcontroller alert the users by buzzer sound. The buzzer sound frequency will change as obstacle close the circuit means it beeps quickly if it too closes with obstacle. Thus, slow or fast beep shows the presence of obstacle with rough idea of obstacle’s distance. Thus, our project allows for obstacle detection as well as pot holes in road if any to the blind person.
  2. It also detects and gives different buzzer sound for water presence alert if it detects water via water sensor attached with it.
  3. There is also a light sensor which detect if there is light or dark. So that user doesn’t go outside at night.
  4. There is GPS-GSM also integrated in this project so that if blind person has gone in wrong direction or area then he has to just press a button of blind stick. This will automatically access the location via GPS mode and sends message to his relative one via GSM modem. Thus, his relate can go to him for search with help GPS location.



1. High sensitive
2. Works from anywhere
3. Low cost and reliable circuit


1. GPS Location
2. Obstacle detection

How To Choose Best kit for You

1. Professional Kit

this kit for Professional person who knows project soldering, testing, assembling and some basics knowledge. In this kit our role is to provide PCB fabrication, microcontroller programming (If any), Project designing and documentation. Our responsibility is limited to according to checklist facilities only. User is responsible for further process like soldering, assembling etc to complete the project. (Do it yourself 70%)

2. Assembled kit

this kit is fully assembled and tested by us for final running. It has prepared for instant requirements and Ready to Use

3. Combo Kit

there are two separate kits, one fully assembled and tested kit. The second one is a Designed & Drilled Copper PCB with soldering components except a set of detachable components which is already attached in first kit (assembled). User can complete the second kit according to assembly procedure given by us in their college practical lab. If user could not complete their project then he/she can use our first kit or make correction by analyzing and comparing with first kit. (Do it yourself 50%)

4. Learning Kit

this kit is fully Do it yourself under our live guidance & support at our workshop or online video calling. We guide how can component has to be place on PCB and solder to it. We continuously checks and guide if any mistaken by user step by step till completion of project. And after successfully completion of project we certify to student that he/she complete their project successfully in our guidance and also provides our company certificate for this.
