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
