Our aim here is to use Octave to configure the mangOH board so that it uploads its light sensor value to the cloud every two minutes. Our aim here is to use Octave to configure the mangOH board so that it uploads its light sensor value to the cloud every two minutes.
# Heartbeat # Preconfiguration
In Octave, display **Resources** page: Ensure that [mangOH welcome application is disabled](settingup/Disable welcome application) and that heartbeat and developer mode are configured as described in [this page](settingup/Heartbeat and developer mode).

Set following resources:
* **cloudInterface/store_forward/heartbeat_on_empty**: **true**
* **cloudInterface/store_forward/period**: **60**
This guarantees that the board contacts the cloud every 60 s at least. Thus, we are sure to be able to download a new configuration to the mangOH board, even if we disable all data uploads and developer mode (see below).
[Reference](https://docs.octave.dev/guides/control_edge_data/control_device_comm/#configuring-and-understanding-heartbeat)
# Developer mode
To check system behaviour in real conditions, we disable developer mode:
* **cloudInterface/developer_mode/enable**: **false**

## Sensor
The light sensor is component U506 (see section 2.1 of [mangOH Yellow Hardware Architecture Guide](http://mangoh.io/uploaded-documents/Reference/mangOH%20Yellow/Discover/HW%20Reference%20Manual/41113116%20mangOH%20Yellow%20HW%20Guide%20-%20HTML5-Responsive%20HTML5/#t=41113116_mangOH_Yellow_HW_Guide_-_HTML5%2FHardware%2FHardware.htm)).
