LED Matrix Based Amharic and English Digital Learning Display System for Children with Remote Control
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 2
Abstract
— Light Emitting Diodes (LEDs) offer the advantages of long life, low cost, efficiency, brightness and a full range of colours. Due to these properties, they are today widely used for all kinds of displays in electronic devices. In this project a digital learning display has designed especially for the children in rural areas from which they can Amharic and English alphabets and numbers. The display is formed 8×8 dot matrix displays so that the designed character patterns are attractive to the children. The display can be hanged on the wall and children can control the display by remote control. A button in the remote can switch the display one of the modes among Amharic and English alphabets and numbers. After selecting a mode, user can go to next or previous alphabet or number by pressing another two buttons of remote. Each alphabets and numbers has been associated with sound so children could pronounce each alphabets and numbers easily and correctly. The system can also be used as a music player to play music’s for Kids. Only 5V DC battery is enough to drive the display. The power consumption of the display is very low. So, schools at the city as well as remote areas where electricity is not available can easily use this display to make the learning more enjoyable to the children. PIC16f877A microcontroller is used to control the display and generating different character patterns. The aim of this study is to develop a digital learning device to display alphabets and characters of both Amharic and English languages using a technology that is easy to obtain and keeping the cost low to make it affordable to any user. The device consists of a PIC16f877A microcontroller, NEC protocol IR remote control, 8x8 LED matrixes, speaker, and SD card.
