Projeto - Bobina de tesla que toca músicas com arduino e Flyback, circuito explicado.

Veja neste tutorial como montar uma pequena máquina que toca música a partir de pequenos arcos voltaicos. É um experimento simples de fazer, porém muito interesante. Aprenda muito sobre, transformador, oscilador hartley, eletromagnetismo e programação com este impressionante projeto. Tenho absoluta certeza que se você seguir tudo rigorosamente você sairá daqui com um projeto legal e um belo sorriso no rosto!

Então projetistas, bora projetar!

Para que o arduino compile esses códigos, antes é necessário adicionar a biblioteca "pitches.h". Deixei tudo pronto para você adicionar, não extraia a basta, basta baixá-la, abrir a IDE do arduino ir em Sketch, Include Library, Add .zip library e abrir a pasta zip que você baixou, e pronto! 

Programas para tocar músicas no arduino:
