        basic.showIcon(IconNames.ArrowNorth)
        direction = "North"
    } else if (degrees < 135) {
        basic.showIcon(IconNames.ArrowEast)
        direction = "East"
    } else if (degrees < 225) {
        basic.showIcon(IconNames.ArrowSouth)
        direction = "South"
    } else if (degrees < 315) {
        basic.showIcon(IconNames.ArrowWest)

    } else {
        basic.showIcon(IconNames.ArrowNorth)
