Zefbot I just wanted to add I also had trouble initially getting this to work correctly. The common 'fault' of it showing all LED's lit but nothing else happened. This is mostly likely a voltage issue. I was using two CR2032 but they must have been old and weren't putting out enough voltage (note that they measured 3V out of circuit but under load they weren't producing 3V each). When I tried two new fresh batteries it worked.
