I have another device with a relay, and I want to use the IOIO to sense the state of that relay.
I thought I would connect the input of the relay to the 3.3v pin, and connect the output of the relay to a GPIO pin. I this way, the GPIO pin will read 0v when the relay is open, and 3.3v when the relay is closed.
