How to Configure VEX IQ Sensors - VEXcode IQ Blocks

When starting to program with VEXcode IQ Blocks, Sensor blocks will not appear in the Toolbox until a sensor has been configured.

Here are the different options when configuring a sensor:

  • Adding a Sensor
  • Changing a Sensor’s Port Number
  • Renaming a Sensor
  • Deleting a Sensor

Adding a Sensor



To configure a sensor, select the Devices button to open the Devices window. 



Select “Add a device.”


Select a sensor.

Note: Sensors include the Bumper Switch, Distance Sensor, Gyro Sensor, Touch LED, and Color Sensor. All sensors follow the same configuration process.


Select which port the sensor is attached to on the VEX IQ Brain. Ports that are already configured for other devices will be unavailable. Once the port has been selected, select “Done” to submit the device to the configuration or “Cancel” to return back to the Devices menu.

Note: Selecting “Cancel” will undo any changes you have made to the device and will not be a part of the configuration.



Changing a Sensor’s Port Number

You can change the port number for the Sensor by selecting on the Sensor in the Devices window.


Select a different port on the Port Selection screen and the port number will turn green. Then select Done to submit the change. 


Renaming a Sensor

You can also rename the sensor by changing the name in the text box at the top of the Port Selection screen. If you select an invalid name, the text box will highlight red to indicate. Then select Done to submit the device changes to the configuration. 


If you change the name of a sensor that is already being used in your project, you will need to update the sensor name in the Block to the new name using the drop down.



Deleting a Sensor

Sensors can also be deleted by selecting the “Delete” option at the bottom of the Port Selection screen.

Note: If you delete a sensor that is already being used in your project, your project will not work until you also delete the blocks that were using the deleted sensor.
