Hi, I am attempting to help my son with his Pi-Top and the Sunfounder sensor kit. He has the proto board, and ribbon cable to a bread board. Attempting to run the first example, a simple dual colour LED, we are struggling to get anything to light up. Looking at pi-top proto display, I can see that GPIO17 is solid red and GPIO18 is flashing, but we are getting nothing from LED. Any ideas for troubleshooting the proto board or gpio pins would be most welcome :)

Ignore me, after some tinkering and trying the proto board directly, we have diagnosed that the ribbon cable is wired backwards. By introducing an awkward twist to the cable we have got it to work on the breadboard too 
