UPM module for the Grove relay switch. The Grove relay is a digital normally-open switch that uses low voltage or current to control a higher voltage and/or higher current. When closed, the indicator LED lights up and current is allowed to flow.

    // Create the relay switch object using GPIO pin 0
    upm::GroveRelay relay(0);
    // Close and then open the relay switch 3 times,
    // waiting one second each time.  The LED on the relay switch
    // will light up when the switch is on (closed).
    // The switch will also make a noise between transitions.
    for (int i = 0; i < 3; i++) {
        relay.on();
        if (relay.isOn())
            std::cout << relay.name() << " is on" << std::endl;
        upm_delay(1);
        relay.off();
        if (relay.isOff())
            std::cout << relay.name() << " is off" << std::endl;
        upm_delay(1);
    }
    // Delete the relay switch object
