Abstract

In computer technology, integrated circuits have been developed and microcontrollers, which can be produced in very small sizes, have become an integral part of scientific research and daily life. Automation, robots, internet of things (IOT), development cards, sensors, transceivers, motors, led/lcd technologies have been products that information technologies have introduced into every stage of life, especially production. Microcontrollers are embedded systems used in numerous fields such as agriculture, health, medical, robotics, television, radio, remote control technologies, armament, industry, automobile, mobile phone. The correct use of these technologies will primarily benefit humanity, and the increase in their use will greatly increase the competitiveness of societies at the national and global level. In this study, a low cost, small size, low power consumption and high performance scrolling text system was designed by using embedded system technologies and wireless data transmission. Arduino UNO board is used to control this design. A scrolling text screen was created with 2 dot matrix LEDs placed on the front. HC-06 bluetooth module card is integrated into the embedded system. With the mobile application developed through the MIT App Inventor (Massachusetts Institue of Technology Application Inventor) program, information was transferred to the system via the mobile application.

Gömülü Sistem Tabanlı Bluetooth Kontrollü Kayan Yazı Devre Tasarımı

Abstract

Bilgisayar teknolojisinde, tümleşik devre geliştirilmiş bu sayede çok yaygın olarak küçük boyutlarda üretilebilen mikrodenetleyiciler, bilimsel araştırmaların ve günlük yaşamın ayrılmaz parçaları haline gelmişlerdir. Bu çalışmada, gömülü sistem teknolojileri ile kablosuz veri iletimi kullanılarak düşük maliyetli, küçük boyutlu, düşük güç tüketimi ve aynı zamanda yüksek performansa sahip kayar yazı sistemi tasarlanmıştır. Bu tasarımın kontrolünde Arduino UNO kartı kullanılmıştır. Ön kısma yerleştirilen 2 adet dotmatrix led ile kayar yazı ekranı oluşturulmuştur. Gömülü sisteme HC-06 bluetooth modül kartı entegre edilmiştir. MIT App Inventor programı vasıtasıyla geliştirilen mobil uygulama ile sisteme mobil uygulama üzerinden bilgi aktarımı yapılmıştır.

Keywords
