Basic UPM module for the Grove button

    // Create the button object using GPIO pin 0
    upm::GroveButton button(0);

    // Read the input and print, waiting one second between readings
    while (1) {
        std::cout << button.name() << " value is " << button.value() << std::endl;
        upm_delay(1);
    }

    // Delete the button object
