Monitoring Variable and Sensing Values in VRC Virtual Skills

Variable and sensor monitoring available in the VEXcode V5 Monitor Console provides important visual cues that allow the user to see what is happening in a VRC Virtual Skills project in real time. The Monitor Console allows users to make a visual connection between the project and the actions of Moby, the Hero Bot. Monitoring sensor and variable values in the Monitor Console allows the user to view real-time reports of a specific value (or multiple values) in a project. Monitoring also helps users to visualize the flow of the project by showing blocks that may not be explicitly reported in the Virtual Skills Window.

The following article will cover:


How to Use the Monitor Console

The Monitor Console reports Sensor and Variable values.

Blocks from the Sensing category in the tool box can be added and removed from the Monitor Console by selecting and deselecting the corresponding check box.

Variables can be added and removed from the Monitor Console by selecting and deselecting the corresponding box. VEXcode V5 always begins with a “myVariable” variable. For information about adding a new variable and variable naming in VEXcode V5, click here.

Lists can also be added to the Monitor Console. Before being added to the Monitor Console, lists and 2D lists must be created.

To add an existing list or 2D list, select the “Add Lists” button.

Existing lists can be added and removed from the Monitor Console by selecting the corresponding check box. The selected list will then appear in the Monitor Console.

To remove a list from the Monitor Console, select the “Add Lists” button again and uncheck the list you want to remove.


Monitoring Sensor Values

Monitoring sensor values in the Monitor Console allows the user to view sensor data in real-time.

In the "Monitoring Sensor Values" Example Project, the status of the Bumper is monitored in the Monitor Console. The project directs Moby forward until the Bumper is pressed by the Mobile goal. The Forks then pick up and drop off the Mobile Goal.


Monitoring Variable Values

The Monitor Console can also be used to monitor variable values. The Monitor Console can provide real-time reports of a specific variable in a project.

In the "Monitoring Variable Values" Example Project, the “spinAmount” variable is used to monitor the spin degrees of the ForkMotorGroup. The variable monitoring on the Monitor Console can help to provide real-time feedback from Moby's motors.
