Inspiration

To assist blind/non-blind people with learning braille through our machine.

What it does

Accepts a string input on the Arduino serial monitor and converts that to braille, so you can learn letters and words. Our program converts the letters and punctuation to braille and then controls 6 six servo motors that create bumps on the surface to simulate braille.

How we built it

We built it using Arduino, cardboard, a little bit of soldering, wires, tape, six servos, and a lot of love. We wired up the servos to PWM pins on the Arduino, wrote a program on the Arduino development environment, and uploaded it to the Arduino.

Challenges we ran into

Finding a proper power supply for six motors, finding room LL89, and integrating a user friendly front end application in replacement of the Arduino serial monitor. Also learning syntax for Arduino and how to get input from the serial monitor.

Accomplishments that we're proud of

It works! The physical braille piece works and we are really excited about that.

What we learned

How to get input from serial monitor, arrays in C++, using the Servo library. Also using react to create a user friendly interface.

What's next for Braille Buddy

Duo lingo with Braille. Creating a user friendly front end application. More compact, more structural encasement for the motors.
