Arduino + SD Card
Murilo eu tenho uma estação da spark fun, e os codigos de um LM35, RHt03 e um BPM085 todos os sensores e codigos eu consegui testar de forma separada porem não consegui juntar todos os codigos em um só, para rodar simuntaneo, vc poderia me ajudar...?

Quem tem dois tem um.
Quem tem um não tem nenhum.... rssssss
Olá Marcus, tenho um código de um projeto que eu iniciei a um tempo atrás. É um arduino conectado a um DHT11 e a um BMP180, registrando em um SD Card.
Bom dia Murilo.
Tenho um DHT22 e u, BMP180.
Pode disponibilizar este código?
Olá, passo sim. Assim que chegar em casa eu mando.
Att Murilo LN
Obrigado
e-mail = nogueiramarcus@ymail.com
Marcus, o código está no meu PC, e só vou ter acesso a ele sábado. Pode ser?
Desculpe a demora.
Bem-vindo a
Laboratorio de Garagem (arduino, eletrônica, robotica, hacking)
