Arduino is a microcontroller platform for non-IT major students, and is widely used as a learning tool. Several AVR series microcontrollers are used in Arduino boards, but ATmega128 is not used. ATmega128 is widely used because of its high expandability and competitive price compared to ATmega328 and ATmega2560 used in Arduino boards. Therefore, by allowing ATmega128 to be used in an Arduino environment, the usability of existing hardware and the Arduino platform can be improved. In this paper, proposed are an Arduino-compatible board design based on ATmega128 and ways to use the ATmega128-based board. As the strengthes of the Arduino platform can be used while utilizing existing hardware in the proposed extension, it is expected that the proposed one can be used in various microcontroller-related education and enhance the learning efficiency.

Arduino is a platform designed for non-experts to easily utilize microcontrollers for various projects. In an educational environment, various boards running on the Arduino platform are used for software education, but ATmega128, which was widely used before Arduino, is not being used. In this paper, we make an Arduino compatible board based on ATmega128 microcontroller and check the operation on the Arduino platform.

Arduino is one of the commonly used microcontroller platforms, and widely used not only in education but also in industrial fields because it enables rapid development and has excellent expandability. However, since there are only a few microcontrollers officially used by Arduino, attempts have been made to use various microcontrollers in the Arduino environment. As part of the Arduino expansion, in this paper, we implemented 128duino, ATmega128-based Arduino-compatible board, and its operation was verified. ATmega128 is one of the microcontrollers commonly used for educational purpose, so it was chosen for Arduino expansion. Since 128duino has advantages in terms of hardware configuration and price by implementing serial and ISP style upload with one USB connection, it is expected to be used in various environments including Internet of Things as well as in education.

Generally, it is not easy to learn guitar fingering for beginner. In this paper, therefore, we attach LED to flat board of guitar to more easily teach the beginner and also implement LED control system that can connect ATmega 128 in order to drive LED attached to guitar. The guitar's flat board is connected with ATmega 128 as communication method of Zigbee. We also develop UI that easily can be learned code and playing for guitar, programmed by guitar fingering and perform the research for guitar fingering using LED.

Recently, remote controls for home appliances have been produced as many as the number of home appliances per household, and new home appliances are being released, but the number of new remote controls is continuously increasing due to their separate functions. Therefore, it is not inconvenient for first time users to use many remote controls because it is difficult and bulky. In recent years, the practical use of a universal remote control, such as large companies such as SAMSUNG and LG are producing a variety of forms. In this paper, we explain how to transmit and receive data format and infrared remote control through custom code identification method used in IR remote control for each company, and to see the size, characteristics and difference with ordinary remote control through ATmega128 remote control experiment. The ATmega128 can be used to control various home appliances displayed on the LCD. As a result, it can be seen that the number of remote controllers having only each function is reduced, and the integrated remote controller using ATmega128 Can handle household appliances.

In this paper, we implemented an wireless data logger system for checking gas volume data using microcontroller Atmega128. The system used wireless communication between master and slave, and operated by socket communication under TCP/IP protocol between server and client. And monitoring interface program was implemented as a software adoptable for GUI environment using Visual C++. The system is constructed server program and client program in order to display gas volume data at a real time, and is expensive, tiny, and easy in implementation. It allows the system to be useful as a pilot project for microcontroller experiment.

In this paper, we designed and manufactured an automatic control system to minimize or avoid damage by automatically controlling ship engines in case of fog to allow for safer operation. This automatic power control system uses ATmega128 and an RPM detection circuit to measure RPM changes by artificially generating fog in the fog generator. For this purpose, we have created a complete schematic and applied our source code to an ATmega128 for PWM control using a Hall sensor motor. In future, an experiment and safety evaluation using this automatic power control system with an actual ship will be prepared.
