Sobre o Projeto

Visão Geral

Este projeto demonstra como reproduzir o tema de Giorno (Il Vento Doro, de JoJo's Bizarre Adventure) utilizando duas placas Arduino para sobreposição precisa de notas. Aproveitando a função nativa tone() e um handshake digital simples, o sistema sincroniza ambas as unidades para tocar notas sobrepostas em tempo real.

A placa principal emite um pulso de gatilho no pino 2, que a placa secundária recebe via pino 3. Cada placa executa um array de forma de onda dedicado, garantindo que notas de oitava mais alta sejam tocadas no segundo Arduino para evitar clipping de frequência.

Esquemático

O diagrama de ligação mostra a conexão dos alto-falantes via transistores MOSFET aos pinos 6 de cada Arduino, com o pino 2 do Arduino primário conectado ao pino 3 do secundário para sincronização. A alimentação dos alto-falantes é feita pela fonte de protoboard (5V).
