| Summary: | Nowadays, most people prefer to use calculator as it is the easiest machine to perform their calculation. However, using
calculator would not illustrate how the calculation was performed. On the other hand, abacus illustrates the steps to perform
mathematic operations, although it takes time to learn. To decrease the time spending in learning the abacus, electronic abacus
or E-abacus is introduced. The main objective of this project is to make E-abacus easy to learn and use. The idea of the
proposed device is to combine the traditional abacus with the calculator. E-abacus can perform two tasks; displaying number
according to the beads and four basic mathematical operations which are addition, subtraction, multiplication and division.
The hardware used in development of E-abacus are Japanese abacus (Soroban), Arduino Mega microcontroller, and Infra-red
(IR) sensor. Open Source Arduino software (IDE) is used to program the microprocessor using C language. From
observations, E-abacus evidently can operate successfully to perform mathematical operations. |
