A couple of the earlier tutorials seemed to work fine. Then I got to this one.
Running the “animations” example from:
I get the expected green ball that moves down and purple ball that moves up, but after 1-2 bounces, the entire unit just spontaneously resets. I get another 1-2 bounces and a reset. Endlessly.
Peeking behind the LCD I can see the blue LED lit dimly while the animation is running (or flashing very quickly, maybe) then a bright flash upon every reset.
