Meloodia mängija
https://www.tinkercad.com/things/6NPMZ0yEs3n-spectacular-fyyran
Tööpõhimõte Meloodia mängija :
- Piezo teeb meloodiaid. Potentsiomeeter sisaldab ja lülitab LCD-ekraani välja. Töö tulemusena moodustuvad ekraanil joonistused ja meloodiate nimi.
Komponeendid Meloodia mängija :
- 1 1602 LCD ekraan ;
- 1 potentsiomeeter ;
- 18 juhtmed ;
- 1 piezo ;
- 1 resistor ;
- 1 Breadboard Small ;
- 1 Arduino Uno R3
Laulud/pildid :
- Imperial March – hat
- Mario Brothers – coin
- Morning – sun
- Hymn CCCP – star
- Christmas song – tree
- JingleBells – bell

Kommentaatorid (uued võimalused) :
char notes[] = “cdfda ag cdfdg gf “; – tähed on noodid ja tühik on paus. Rütmi seadistamine.
int beats[] = {1,1,1,1,1,1,4,4,2,1,1,1,1,1,1,4,4,2}; -“tempo” meloodia kiirus. Kui väiksem tempo_ siis suurem kiirus.
delay(tempo/10); – väike paus nootide vahel
Arduino tone() – noote tihedus
Näiteid elust :
- Muusikakarp
- Veermik
- Muusikaline tagasitõmbamine
