Hello everyone. I am doing a proyect in which I had to make the zeus car kit park itself. I bought the model and i modified it a bit adding 2 extra ultrasound sensors at the back and right side of the robot. However, i am having problems with the program because every motor and sensor is connected to the shield plate, the one who goes above the arduino 1 plate, and normal programs dont work. I need help because i am stuck in here and i should end this proyect as early as i could. I will put here the url to the kit i bought.

Our Zeus automotive expansion board does not have any extra pin interfaces for adding additional sensors. How did you connect them?

Additionally, to add extra sensors, you would need to edit the program for them to function properly. Therefore, we do not recommend adding extra sensors, and we do not have related code support.

If you are following our assembly instructions and encounter any issues, please provide us with detailed information (such as images or videos of the problem) to help us analyze and resolve the issue.

I used the pins of the rgb lights, connecting the sensors with the extra cable and the other one using the cable of the rgb lights creating my own cable by cutting the rgb and adding a connector. As you say, i would have to edit the program, thats my problem.
