 * The LED is used to represent sensor options, the user can press A to select one; which starts logging.
 * Or press B to move onto the next one.
 * 
 * Logging happens every second and is indefinite. The user may cancel the logging via the B button.
 * 
 * Whilst the sensors are cycled between the sensor being displayed may dynamically update if the readings from that sensor are in excess.
 *      See .dynamicSensorSelectionLoop()
 *      It checks all sensors inside UI_SENSOR_SELECT_STATE; if there is one that has a reading beyond the threshold then it will switch this.uiSensorSelectState to that sensor.
 *      This allows the user to cycle between UI elements phsyically - by shining light on or shaking the microbit.
