So I had it working, everything was fine, but now its not =/
I have an Arduino Duemilanove board running on a 12V battery that is connected through VIN and Ground. The Power led is blinking really fast so that it looks like its just dimming, and the load light is blinking slower but still really fast... I took out my multimeter and got a steady 12.7V going into the board so the power source is not fluctuating... Any ideas?
