Variable and Sensing Values Monitoring in VEXcode GO

Variable and sensor monitoring available in the VEXcode GO Monitor Console provides important visual cues that allow the user to see what is happening in a VEXcode GO project in real time. The Monitor Console allows users to make a visual connection between the project and the actions of the GO Robot. 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 Playground Dashboard.


How to Use the Monitor Console

To open the Monitor Window and view the Monitor Console, select the Monitor icon next to the Help.

The Monitor Console reports Sensor and Variable values.

Blocks from the Sensing category in the Toolbox can be added to the Monitor Console. First, select the parameter to be monitored in the block within the Toolbox.

Next, select and drag the block to the Monitor Console icon in the Workspace.

To remove sensor values from the Monitor Console, select the 'X' icon.

Variables in the Toolbox can be added to the Monitor Console by selecting and dragging the variable block to the Monitor Console icon in the Workspace. VEXcode GO always begins with a “myVariable” variable. For information about adding a new variable and variable naming in VEXcode GO, 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 and drag the associated list block to the Monitor Console icon in the Workspace.

If the incorrect block is dragged to the Monitor Console icon in the Workspace, a red icon will appear over it, signifying the wrong block was chosen and cannot be monitored.

Monitoring Sensor Values

Bumper example.png

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

In the following example, the <Pressing bumper> block is being monitored in the Monitor Console. The project directs the GO Robot to stop if the LED Bumper comes in contact with a wall or other object (pressed). Watch as the value of the <Pressing bumper> block in the Monitor Console changes from false to true when the LED Bumper comes in contact with an object.

Timer example.png

The Monitor Console can also be used to help the user visualize the flow of the project by showing blocks that may not be explicitly reported in the Playground Dashboard, such as timer in seconds.

In the following example, the (Timer value) block is being reported in the Monitor Console. The GO Robot will drive forward 400mm and then wait until the (Timer value) block reports back a value greater than 3 seconds. The GO Robot will then turn right 90 degrees. Without the Monitor Console, the user would be unable to visualize the exact timing of the turn right 90 degrees command.


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 following example, the “timesRepeated” variable is used to monitor the number of times the GO Robot repeats a certain behavior. The variable monitoring on the Monitor Console can help to provide real-time feedback to understand the flow of the project.
