how it works?

WITH ENGINEER'S APPROACH

Solenoids

foam ball

6 solenoids are used as braille display, which is sorted as 3 x 2.The braille display can just display just like braille pattern when user gave inputs. The user will feel the solenoids being pushed up.

Foam ball is used to hold the solenoids. With foam ball, users are able to hold the translator in a more comfortable and easier way.

ARDUINO UNO R3 WITH ACRYLIC CASE

BLUETOOTH MODULE HC-06

By using a programmable device, we were able to compile code and make the translator work. Arduino will translate the user input via Bluetooth and produce an output with the solenoids. Connect the user’s smartphone (Android Platform) to the Arduino by Bluetooth. User are able to send messages that they want to translate once they paired with the Arduino.

Sponge

BREADBOARD

Sponge is used as a case and to protect the circuit board from shock.

Breadboard because the circuit can be easily being modify and damaging of the electronic component would not happen (prolonged soldering will have burnt the electronics)

Wires

9v battery

Long wires were used so that it can be easily be adjusted by the user. These will allow user to move their hand freely without constraint.

9V battery can be easily gained in the market. 9V battery is used to power the Arduino.

Velcro Strap

11.1V Rechargeable Lipo Battery

The position of all the components (Arduino, Battery and the circuit) are able to be adjust based on personal preference, which made user of all sizes of arm to use it with comfort.

Rechargeable Lipo battery is used because the braille display required high and consistent voltage to work.
