Description as a Tweet:

The smart watch detects the distance of the nearest obstacles and beeps or vibrates to notify the user of upcoming hurdles. It further also states the contact of emergency in-case someone forgot their whereabouts (as it happens in Dementia).


We were inspired to make this smart watch because there are so many people who have disabilities such as having hearing impairment, and/or are blind. In order to help these disable people we created this smartwatch that helps a lot of the disable people overcome obstacles that they face in their everyday life.

What it does:

The purpose of this project is to help the disable people and protect them. The watch measures how far in centimeters an object or a person is and when it comes 50cm close, the buzzer starts beeping and when the object or person comes 20cm closer to the disabled person it starts beeping a little faster then before, letting the disabled person know that an object or person is closed to them. We also have an emergency contact number on the smart watch in case the disabled person gets lost or they have big diseases like Alzheimer.

How we built it:

We build the smart watch with an LCD, ultrasonic sensor, microcontroller (arduino), and a buzzer(speaker). Basically, the ultrasonic sensor detected how far an object or a person is from the disabled person and the LCD would read the distance in centimeters letting the person know. The ultrasonic sensor is able to detect the distance because a frequency output and then it bounces back from the object, which ultimately tells the distance.

Technologies we used:

  • Objective C
  • C/C++/C#
  • Arduino
  • Microcontrollers
  • Other Hardware

Challenges we ran into:

There were many problems we faced such as finding an idea and decoding software and hardware. It took us more than two hours to come up with an idea because my hacker partner and I would come up with ideas and sometimes we both didn’t like them or one or the other didn’t but eventually we infused all our ideas together to create this smart watch. Another challenge we faced was decoding our software and hardware. We had to figure out what the problem was in our hardware and software, which was the reason why nothing was showing up on the LCD screen. However, we eventually figured it out. At the end of the day, teamwork, determination, dedication, and the enthusiasm to learn something new is what keeps us going to help society in a positive way.

Accomplishments we're proud of:

We are really proud that we were able to complete the project that we planned on time. It was a great experience for my group because we learned a lot and implemented that in our project.

What we've learned:

We learned how an ultrasonic sensor works and how it releases this frequency and it bounces back from an object, which tells us the distance. We also learned that it’s essential to have our breadboard neat and clean as much as possible so that it’s easy to understand where each wire goes too. Also, in the software side, we got to experience how an Arduino ide works and we were able to code in that software for this project and learn a lot about it’s syntax and the programming techniques.

What's next:

In the future, we believe that in our arduino program we could make user interfaces where we can input their information and update it. Also, making the hardware in a printed circuit board, making it user friendly for every disabled person to use.

Built with:

We used an ultrasonic sensor, LCD, microcontroller(Arduino), and a buzzer(speaker).

Prizes we're going for:

  • Nintendo Switches
  • Apple AirPods 3rd Gen
  • $500 total to the winning team
  • Amazon Echos
  • Meta Portals
  • Bose Headphones
