Inspiration I had problems as a biker, with people wearing headphones, and not aware of my presence

What it does using sonar, it gives feedback to the box, vibrating faster and more frequently the closer it approaches an obstruction from 3 feet in

How I built it, I connected the Ping to the arduino, developed code to measure space and give feed back every 1 second, then developed a ration code for the vibrator. then

Challenges I ran into Compacting everything into a sleek package, along with shorting the technology and having to get replacement. Also balancing the 3V and 5V objets from the same arduino

Accomplishments that I'm proud of completing a working, simple product

What I learned arduino language

What's next for Theia, creating a smaller version to attach to the back of shirt collars, to warn people of approaching objects from the back.
