The Musical Phonics Board
Source: Stemoto Original
Touch physical wooden letters wrapped in copper tape to trigger their corresponding phonetic sounds (or Hindi Matras) through a speaker attached to the micro:bit. A multisensory language learning tool that connects tactile feedback with audio processing.

Step-by-Step Instructions
Prepare the Letters
Wrap each laser-cut wooden letter in copper tape so it becomes conductive. Mount the letters on a cardboard base board in alphabetical order.
Wire the Connections
Use crocodile clips to connect each letter's copper tape to a different pin on the micro:bit. The child's body will complete the circuit when they touch a letter while holding the ground wire.
Program the Sounds
In MakeCode, program each pin: when Pin 0 is touched → play the 'A' phonetic sound ('ah'). When Pin 1 is touched → play the 'B' sound ('buh'). Use the built-in speaker or connect an external one.
Touch and Learn
The child touches each letter and hears its sound immediately. They can practice spelling simple words by touching letters in sequence: C-A-T.
Hindi Mode
Swap the English letters for Hindi vowel matras (अ, आ, इ, ई). Reprogram the micro:bit to play the corresponding Hindi phonetic sounds. Bilingual phonics!
Why It Works & Notes
Multisensory language acquisition at its best — children touch a physical letter (tactile), hear its sound (auditory), and see the letter shape (visual) simultaneously. This triple encoding dramatically improves letter-sound retention compared to flashcards alone.
NEP Alignment: Multisensory language acquisition; connects tactile feedback with audio processing. Curriculum Mapping: Language (Phonics, Letter Sounds, Matras). Target Level: Class 1.
