Rubbish birthday for my son, I’m afraid.
We assembled the mbot 2; but we find that if we unplug the usb cable, it immediately turns off - it’s as if the mbot 2 shield holds no battery power. However, the pi controller, when connected to the shield and USB cable, shows full battery.
When we unplug the pi, and turn on the shield there are no lights, no nothing…
I’m really stuck. have to get the kiddo another present now, as this has been somewhat a disaster, I’m sad to say - fortunately, he’s a good kid, so he’s understanding - better lad than I, that’s for sure ; would like to not throw this all away in the long run - only good for trash can now, afaict., can someone help?
