PelletMonitor

The PelletMonitor (Aeon.Foraging) node monitors the current state of pellet delivery commands and the beam break. Within this node, pellet delivery commands received by the Harp output expander are filtered from the “PatchEvents” Subject and successful deliveries monitored through the “PelletDelivered” Subject (e.g. “Patch1PelletDelivered”). The RepeatEverySubject node ensures this node is only running while an animal is present in the habitat.

Inputs

None

Outputs

Sequence of dynamic class events triggered by deliver pellet commands and beam break events, consisting of a “Timestamp” (double) and a “Value” (boolean) that reports the current state. This “Value” is True if and when a delivery command has been received, and False when a successful beam break is detected.
