Augmented Reality-Based Programming Using Atmega 2560 Microcontroller Trainer Kit Support

ABSTRACT


INTRODUCTION
Developments in the field of knowledge and technology (Science and Technology) have an impact on all aspects of life [1]. In addition to rapid development, change also occurs quickly. Because of this, humans must adapt to manage and utilize education and technology (Science and Technology) proportionally and maximally [2]. Technological progress is something that cannot be avoided in this life, technological progress will develop according to the progress of human knowledge [3]. Humans as users of technology should be smarter in utilizing technology in the era of globalization [4]. The process of adaptation to technology is one way to adjust to education. This is done in giving birth to a new generation that understands the progress of renewable technology [1]. One of the factors that can support the quality of student learning outcomes is the availability of learning media. [2].
The learning method is an operational step of the chosen learning strategy to achieve learning objectives (Sani, 2019). A good learning process must contain interactive, fun, motivating aspects, and provide space for students to develop creativity and independence. Interesting learning media is needed to increase students' understanding of a material besides that problems sometimes arise when access to physical objects is needed to provide an explanation to students of a material, for example material related to microcontrollers. One of the developments media in learning is the media learning using Augmented Reality.
Augmented Reality is an application who combine the real world with the virtual world in two dimension or three dimension form projected into an environment real at the same time. Ilmawan Mustaqim in Raajan (2014) mentions that Augmented Reality was first used in 1957 -1962 by a cinematographer named Norton Heilig, who was named 'Sensorama'. Sensorama is a simulator that can simulate visuals, vibration and smell. This technology can make people get the thrill of exploring and learning, fun and unique because they directly involved in the learning. AR great opportunity in the world of education because students can directly interact with objects contained in this application.
Based on the problems above, the authors found a way to achieve the above goals by making innovations, namely learning methods and applying Augmented reality technology that is closer to the microcontroller trainer kit. on this occasion the author will design and create a tool called "Implementation of Augmented Reality on the AT Mega 2560 Microcontroller Trainer Kit" as a form of solving the problems described above.

RESEARCH METHOD
The type of research used is Research and Development orwith 4-D model development procedure. Research and development used to produce certain products, and test the effectiveness of these products. The 4-D development model was chosen because it has a systematic procedure and in accordance with the background of this research problem.

Tool and System Design
The design of the product design consists of several stages starting from searching and gathering information related to the system, designing the system, making tools to testing, and generating reports. The flow of important research before carrying out system design, which is used to simplify the stages of making tools, will be explained in the form of a block diagram. Starting with a literature study, namely a series of activities related to collecting library data, reading and recording related research, then proceed with designing tools and systems with the aim of preparing what is needed in making tools and systems followed by collecting materials, what materials are needed. used in making tools and systems after the goods are collected, proceed with assembling the tools, in this step the author has started to make a microcontroller trainer kit, after the tools are ready, proceed with making an augmented reality system, and after the microcontroller and augmented reality trainer kits are ready, start by integrating the two if successful proceed to the stage of data collection and preparation of reports.

Design of ATmega 2560 Microcontroller Kit Trainer System
Researchers use the research and development model as a method to produce a microcontroller trainer kit. The design of this study aims to develop a programming training board in the form of a Microcontroller Trainer Kit to support microcontroller programming  Literature study is a series of activities related to library data collection methods, reading and recording and processing research materials that aim to develop tools to be made. Needs analysis is a series of activities to determine the needs or conditions that must be met in a new product or product development that takes into account the needs of users. The product design of the Microcontroller trainer kit is realized in a product design drawing, schematic and a series of product layouts that are in accordance with the needs analysis of the user or learning system, followed by testing by experts if the trainer kit passes the test then the trainer kit will be ready to use.

Previous Research
This research refers to previous literature reviews where a lot of related research has been carried out "Augmented Reality and Trainerkit mikrokontroler AT mega 2560" in the form of the following design and analysis. As a reference, the authors took three journal from several years ago as an improvement for this research. designed to provide users with more detailed information than real objects. Media is a tool or object that functions as a liaison between the recipient and sender of messages. Learning media is an intermediary tool between educators and students in learning that is able to connect, provide information and channel messages so as to create an effective and efficient learning process." [4].

Based on Mustofa Abu Hamid's research in 2020 in his research entitled
Development of a Microcontroller Trainer Kit The trend of the industrial revolution 4.0 has made microcontrollers increasingly in demand to be developed and even every educational institution has begun to study in depth in the field of microcontrollers to be included in education, This research with the title Application of Augmented Reality on Microcontroller Trainer Kits has several advantages over previous studies. In this study, the microcontroller used was the Arduino AT mega2560 where the advantage of this Arduino is that it has many pins and this research adds an augmented reality system to optimize the learning process.

RESULTS AND DISCUSSION
From the discussion above, it is found that this tool focuses on learning programming using the Atmega 250 trainer kit. In order to make learning more interactive, interesting and efficient, augmented is one of the media that is suitable for use. The following is a discussion regarding the working system of the Atmega 2560 Trainerkit tool with Augmented Reality support :

Trainerkit Mikrokontroler Function
Trainerkit can assist students in understanding each concept explained through visual media (images/videos) as well as written/text. With the existence of a trainer kit, all material or concepts that are still imaginary (imagination) can be realized in real terms so that they can be carried out in real practice. The trainer kit also helps improve students' skills and creativity, because by using a trainer, it is easier for students to explore and try several practicums with various variables.

Product Description
In the process of designing the microcontroller trainer kit hardware using several components including Arduino ATmega 2560, Regulator 5V and 3.3V, Micro Servo 3.

Hard And Soft Design
This chapter provides an overview of the mechanical, electrical and program appearance of the Arduino software to make it easier for the reader to understand the system printed on the tool.  This microcontroller trainer kit uses the Ardduino IDE software. Arduino IDE stands for Integrated Development Environment which is software for writing programs, compiling and uploading programs to the Arduino board.
