Math Clock: Perangkat Penunjuk Waktu Kreatif untuk Olahraga Otak
Abstract: Brain is one of the
most vital parts for humans, with the number of brain function that is needed
for the body, the brain becomes a very important part of the human body. If
there is damage to the brain will certainly cause the performance of the human
body will not run properly. Because of that, it’s very important to maintain
brain health. There is a way to maintain brain health, for example is by doing
brain exercise. Examples of brain exercise is to do simple math calculations or
doing brain games like sudoku. Because of that, created a tool that can help
the brain to maintain brain exercise. The tool is called math clock. Making
math clock tool consists of hardware and software. The hardware consists of RTC
as real time data input, ATmega328 as microcontroller and dot matrix 32x16 as a
tool to display the output that has been processed by the microcontroller. The
software is built using C with Arduino IDE. Math clock will process the data
from RTC then processed it, in microcontroller so when output displayed on dot
matrix, output will be simple mathematical operation with real time clock data
on it. Test results show that, math clock is capable of displaying a simple
mathematical calculation operations such as addition, subtraction, multiplication
and division. The mathematical operation that display on math clock, appears to
be random, so it’s not triggered by same mathematical operation. In math clock
the display will change every 20 second, so in 1 minute there are 3 different
kinds of mathematical operations. The results of questionnaires of 10 different
students, showed 9 out of 10 students said math clock is a tool that easy to
use as a clock. Math clock will be alternative for doing brain exercise every
day.
