Color Sensor Not Picking up Colors

Hi-I am using the VEX Go codebase. I connected an eye sensor facing down. When I run the program-move forward-if eye sensor detects green turn left, etc. The codebase rolls right over the colored square. I have tried different hues of colored squared, construction paper and felt but nothing is working. Can someone provide a solution?

You would need to share the project you’re using to be able to illustrate if this is a coding issue or a sensor issue. Have you taken a look at the GO Activity Series on using the Eye sensor?

You might want to try swapping the Senso for another one because they don’t work sometimes or switch the open link cable with another.
