  • Although people want to learn guitar easily and happily, it is difficult to learn because many restriction comes from expense, student's efficiency and teacher/s skill. In this paper, the guitar teaching program has been developed for who is difficult to learn guitar fingering. The guitar teaching system with ATmega 128 was programed using visual studio MFC program. The guitar fingering U/I program was investigated for beginners easy to learn the code and playing with guitar.

  • Magnetic levitation system is nonlinear and inherently unstable, so it is difficult to control. Analog control circuit was widly used as the controller of magnetic levitation system, but digital controller is now substituted for analog controller according to development of digital electronics. In this study, Atmel AVR series, ATmega 128 which is a kind of $\mu$-processor for digital controller is used because the chip is cheap and popular. We designed and made ATmega 128 one-board controller and aimed to verify validity through the experiance of levitation response.

  • 최근에 국내외 유명 자동차 업체들은 대부분 자동주차시스템으로 SPAS(self parking assistance system)기능을 도입하고 있다. 실제로, 폭스바겐의 주차보조시스템 '파크 어시스트'는 후진 일렬주차시에 핸들의 조작 없이 주차가 가능한 시스템이다. 본 연구에서는 ATMega를 활용한 모형 RC카 자동차를 활용하여 자동주차 시스템을 구현한다. 모형차량 측면에는 카메라 센서를 부착하고, 범퍼의 모서리 부분마다는 적외선 센서를 부착한다. 주차가 되어 있지 않은 공간을 찾아내는 단계는 Atmega에서 영상처리 기법을 활용하고, 빈 주차공간을 찾은 이후에는 각종 센서와 모터 컨트롤 기법을 활용하여 자동주차시스템을 구현할 예정이다.

  • In this paper, a new robot system is designed and manufactured to improve the educational robot. The main processor is realized using the ARM Cortex-M3 and the co-processor is implemented by AVR ATMega2560 to deal with data coming from sensor modules. The processor of sensor modules was developed by the AVR ATMega8. The communication system is composed with IIC communication to alleviate the load of main processor. We have developed the educational robot system adopting the hub module for extension characteristics.

  • The social networking service (SNS) is free, but the data usage fee paid to the telecommunications company and the member's information must be provided directly or indirectly. In addition, while SNS' specifications for transmitting and receiving devices such as smart-phones and PCs are increasing day by day, using universal transmission protocols in special environments such as contaminated areas or semiconductor manufacturing plants where work instructions are mainly made using short messages is not easy. It is not free and has a problem of weak security. This paper verified the practicality through the operation test by implementing IMCP, a low-power, low-cost message transmission protocol that aims to be wearable in special environments such as risk, pollution, and clean zone based on ATmega128.

  • The Air Quality Sensor(AQS), located near the fresh air inlet, serves to reduce the amount of pollution entering the vehicle cabin through the HVAC(heating, ventilating, and air conditioning) system by sending a signal to close the fresh air inlet door/ventilation flap when the vehicle enters a high pollution area. The sensor module which includes two independent sensing elements for responding to diesel and gasoline exhaust gases, and temperature sensor and humidity sensor was designed for intelligent AQS in automobile. With this sensor module, AVR microcontroller was designed with back propagation neural network to a powerful gas/vapor pattern recognition when the motor vehicles pass a pollution area. Momentum back propagation algorithm was used in this study instead of normal backpropagation to reduce the teaming time of neural network. The signal from neural network was modified to control the inlet of automobile and display the result or alarm the situation in this study. One chip microcontroller, ATmega 128L(ATmega Ltd., USA) was used for the control and display. And our developed system can intelligently reduce the malfunction of AQS from the dampness of air or dense fog with the backpropagation neural network and the input sensor module with four sensing elements such as reducing gas sensing element, oxidizing gas sensing element, temperature sensing element and humidity sensing element.
