Blind children have limited ability to read, so the introduction of the ability to read and write using braille is very important. They have to learn to recognizing braille letters, then arranging letters to form syllables and finally a word. Learning about the concept of reading needs a tool that makes it easy and fun, then children will learn while playing. The design of the device braille set is intended as a learning tool for blind children to introduce and learn to read braille. This system uses an RFID (Radio Frequency Identification) MFRC522 sensor programmed by Arduino as a microcontroller. The code as a signal in the RFID tag card is read by the RFID reader. RFID tag cards are equipped with a layer on the surface of the card marked with a braille symbol. When children recognize the braille symbols on cards, they can assemble the cards into a word. The word will then be read by the device and audible so that the children hear the words they have composed. The components of this learning tool to read braille use an RFID reader component, a mini MP3 player module, Arduino, as a microcontroller. The power supply uses a 9 volt battery. DC motor drive and wheels to walk on the scrabble track. The material for the card coaster casing uses acrylic material. The track frame uses aluminium profiles. Overall, the cost of making braille reading learning tools with the implementation of RFID technology is cheap and affordable.

It is very important for children who have low vision or visual impairment to be able to recognize braille letters and recognize words. This ability will help them to be able to read and write Braille. Braille recognition learning methods currently use technology as a learning aid or assistive device. However, assistive devices with this technology are still rare and unaffordable for some schools and students in Indonesia. The design of this braille learning aid applies RFID as a low-cost solution for learning braille reading aids. This tool integrates several braille learning methods that have been carried out by teachers when teaching braille recognition in schools. The integrated methods are the Mangold method, the Fernald method, the Flashcards method and the scrabble method. This tool helps children recognize braille letters, arrange them as words and is confirmed directly by the tool through sound if the letters arranged as a word are right or wrong. With this integration method, children are expected to be able to learn to read braille while playing, and learn independently.
