5v power supply also connects to 3.3v regulator, which arduino reads, when this drops to 0v turn on led_pin.<\/p>\n

Arduino pro mini based light switch<\/p>\n
Send same on\/off signals as http requests (30\/31)<\/p>\n
3 indicates start bit<\/p>\n
Second bit is state to switch relay.<\/p>\n
Purchase or make two position momentary wall mount switch and wire buttons up to send signals to light.<\/p>\n
Ethernet arduino add motor shield and use directly for blinds control or use separate mini arduino ?<\/p>\n
Undecided. Probably mini.<\/p>\n
Can adapt existing code for light to operate blinds servo or stepper motor.<\/p>\n
And can easily send different control bits from existing code in etherten. Easy to add more sections ! \ud83d\ude00<\/p>\n","protected":false},"excerpt":{"rendered":"
