Controle de Mini System Sony pela internet
Controle seus aparelhos de som da Sony pelo celular
Faça por conta e risco...
Pesquisei sobre o protocolo SIRC da Sony, daí clonei um controle pela entrada do microfone no pc com o programa Audacity (Melhor que osciloscópio)...
Foi utilizado a IDE do arduino, para programar um ESP32, na GPIO 26 utilizar um led IR com resistor de 120 ohms para proteção da saída, utiliza metade da corrente do led, pois o pino está limitado à 12mA e não 20mA que o led precisa, distância funcional sem drive 50 cm.
Programa completo:
// Base do protocolo Sony consultada em https://www.sbprojects.net/knowledge/ir/sirc.php
/*
Aparelho testado HCD-SH2000 100% funcional, extra o comando Eject
100% Compatível com os modelos de controle:
- RM-AMU006 / RM-AMU053 / RM-SC3 / RM-SCU37B
