Grove Starter Kit for Pico

I have been unsuccessful getting going with this starter kit. I am new to this and have downloaded Thonny. None of the projects work.
I had previously downloaded Micropython onto the Pico from another kit. I tried removing this and letting Thonny sort this out but still nothing.

PLease help

Hi, did you follow the step-by-step instructions in the wiki? In addition, you need to confirm whether there are any problems with the wiring (such as loose interface, etc.).
