The secondary power is not being received.

Hi, I am very new to this shield. I have had it for a few days but been very impressed by its performance and had fun playing around editing its example codes ect..

Unfortunately I came into some complications when the shield stopped receiving power from the external supply. It was working fine but then suddenly stopped working.

I tried changing the battery, the arduino, the wires connecting the battery but none of it worked. The arduino I was receiving power but not the shield. The pins of the shield are all in the pins of the arduino I am using a 9V battery.

Do you know what I can do? The shield with one battery occasionally started to output the starting message and then cut out.

Many thanks,

Never mind, I managed to fix this problem by using a secondary power supply from a wall socket (mains plug) instead of using a battery. Are there ways of making it mobile without a mains power supply?
Kind regards,

Yes. I usually use 4 AA batteries that I connect to the Arduino barrel plug.
