Have you been able to drive the robot? I am wondering if you are not getting a light on the Digital Side Card next to the relay block if your cable may be inverse. There have been some in the past that had the connectors on wrong.

Also make sure you have three green power lights on the Digital Side Car.

Attached an image where you can see the light change when you toggle the relay.

Can you share the code where you tried just the relay? The full class if possible.

Thanks!
