Opis projektu
Cieľom projektu je vytvoriť Interaktívnu hraciu dosku so stimulujúcimi podnetmi, určené pre deti so špecialnými potrebami.
Prečo?
- Osobný prínos: práca s Arduinom Uno a s jeho komponentmi
- Spoločenský prínos: Naučiť deti využívať vypínače v domácom prostredí, prostredníctvom našej interaktívnej hracej dosky
Komponenty dosky
Sem príde podrobný návod na výrobu.
- Arduino Uno
- 3 striedavé vypínače
- 3 statické vypínače
- 3 LED RGB modul Keyes 5050
- DFPlayer Mini Mp3 modul
- Reproduktor
- Doska
- Zdroj (externá batéria)
- SD karta
Analýza a popis riešenia
Pre náš projekt, je potrebné, aby sme pozapájali vypínače pre RGB LEDky a pre MP3 modul s SD kartou, ktorá obsahuje mp3 súbory s názvom "000x.mp3" (x = {1,2,3}).
Riadili sme sa podľa tejto schémy na zapojenie vypínačov:
Pri Mp3 module sme postupovali na základe tejto schémy:
Naše výsledne zapojenie môžete vidieť na nasledujúcom obrázku:
Nasledovne sme museli odskúšať funkčnosť našich modelov a bolo potrebné optimalizovať výšku hlasu, ktorá sa nastavovala v zdrojovom kóde. Nasledujúci krok bolo zabudovanie týchto komponentov do dosky s rozmermi 56x56 cm.
Pri prvotnom zapojení sme používali sťahovacie pásky na upevnenie našich modulov.
Avšak nebolo to vhodné riešenie a takisto bolo potrebné zabezpečiť ochranu riadiacej dosky pred vonkajšími faktormi. Tým pádom sme využili ochranné krabice, ktoré sme museli upraviť na vhodné rozmery.
Zároveň sme ich nafarbili na čierno a prilepili upozornenie, že sa jedná o elektrické zariadenie.
Pre lepšiu stabilitu a dizajn sme nakoniec využili skrutky a matice namiesto sťahovacích pásov. Následovne, sme pomocou Vinyl cutter vyrezali potrebné nálepky na vypínače, ktoré spúšťajú zvuky daných zvierat (mačka, kohút, krav). Takisto sme využili laser cutter na vyrezanie priesvitného plexiskla, ktorý slúži ako ochrana pre LEDky. Nafarbili sme ich podľa využitia RGB LEDky (červená, zelená, modrá).
