Abstract

This paper describes about a calculator designed specifically for people with the Blind. Calculators are designed differently with calculators are generally used by people who can see normally. This special calculator uses a microcontroller as a data processor. This special calculator uses several pieces of push button which is compiled based on input braille code. The braille code data will be converted by the microcontroller into the numbers to be calculated. This special calculator using an MP3 Player Module for a sound as a medium to guide blind people to operate this special calculator. Operations that can be performed by a special calculator is operating addition, subtraction, multiplication, division, powers and roots. In addition, a special calculator can also look for the results of the division (DIV) and look for the rest of the division (MOD). The maximum number of digits that can be generated is as much as 8 digits. The number of values can be entered is limited to integers and the calculation results are limited two decimal places. Design and implementation as well as the results of testing on this special calculator indicates that this particular
