New Arduino and Serial LCD problem

just got a new inventor kit & added a serial LCD to it. It took several hours to figure out it probably was not something I was doing, but more than likely, some bad part, somewhere.

I had had similar problem earlier with the tiny motor experiment - did not work at all, then just started working on its own for no reason. On the serial LCD problem, the CPU appears to be working all the time (as evidenced by the serial monitor) but the LCD depends on some random influence.

All in all, the overall reliability of both items has been about a 1 out of 10.

Any suggestions?

Spark is sending a replacement. thanks on that. I’m guessing the motor was just ‘sticky’.
