36. Using GPIO pins
    // Open the GPIO pin for usage
    val gpioPin = peripheralManagerService.openGpio(pin)
    // Direction Input or Output
    gpioPin.setDirection(DIRECTION_OUT_INITIALLY_LOW)
    // When the Pin is classified as Active
    gpioPin.setActiveType(ACTIVE_HIGH)
    gpioPin.setEdgeType(Gpio.EDGE_BOTH)
    gpioPin.registerGpioCallback(someCallback)
    gpioPin.setValue(true)
