PAROLE AL CUBO– an Educational Interactive Game for Children With Dyslexia

Parole al Cubo is an educational game designed to support children with dyslexia in recognizing letters and forming words through playtul interaction. Ine system uses wooden cubes with engraved letters and embedded RFID tags. Children must recreate the word that matches the image shown on the screen using the correct cubes.

This project combines tactile elements and electronics to make learning more engaging and inclusive.

Electronic Components:

• 1x Arduino Uno

• 1x RC522 RFID Reader

• 1x Nextion Basic Display

• 12x Female-to-Male Jumper Wires

• 4x Male-to-Male Jumper Wires

• 1x Red LED

• 1x Green LED

• 1x Micro SD Card

• 27x RFID Tags

• 1x Silver Tape

Physical Components:

• 27x Wooden Cubes

• 4x Laser-cut container parts (see CAD files)

Step 1: Preparing the Wooden Cubes

Use smooth wooden cubes and engrave one letter on each using a laser cutter and the provided

Step 2: Attaching the RFID Tags

Attach one RFID tag to the back of each cube. Make sure the tags are centered and securely fixed.

Step 4: Uploading the Code

1. Open the provided .ino file in the Arduino IDE.

2. Install the MFRC522 library (via Tools > Manage Libraries).

3. Select the correct board and COM port.

4. Upload the code.

The code includes comments to help you adapt it if needed.

Step 5: Loading the Images to Nextion Display

1. 2. 3. Copy the .txt file to a microSD card.

Insert the card into the Nextion (while powered off).

Power it on — the images will load automatically.

To edit or add images, use the Nextion Editor software.

Step 6: Final Assembly & Usage

Once all components are connected and the code is uploaded, the game is ready. The child sees
