December 30, 2012 by Cwatson71	Hello, I just received my nerdkit for Christmas and am going through the initial setup project. When I connect the battery the LCD just flickers, but at regular intervals. @.5 seconds per cycle. I had initially connected the battery to the output pin of the regulator so I am concerned that I cooked something by sending 9V through.
