TTS Shield---ButtonPad
E X T E N D E R SHIELD
U N O -- Battery Pack
To power the Arduino, you must put wires from the battery to the 5V and GND pins on the Arduino, but the extendershield blocks them and the Battery has nowhere to put the wires. I see a row of pins labeled 5v, GND and 3V on the top, but I have no idea where to put wires on them. Can you help me?
The backpack blocks the 5V/3.3V/GND holes because it's providing the 5V power; you don't need to add anything additional (while the battery is charged). If you DO want to provide external power than you can plug in a USB cable or supply 5V via the horizontal, female header pins on the backpack.
If you're asking how to provide power from one side of the extendershield to the other side -- you don't have to do anything. Those wires (traces) are already present. The row of 5V/GND/3.3V holes are just extra holes for your convenience.
I mean that the battery assumes you are latching it to the bottom of the Arduino and stringing wires from it to the Arduino's original 5v and GND pins. With the ExtenderShield, those pins are blocked, and I don't know how to power the Arduino now. I know it is possible, as they are made by the same person, he has alluded to the fact that he uses them in conjunction, and he has pictures on his stores of it set up, but it is always a top-down view with no indication as to how it is done.
You can bring those 5V/GND wires to the 5V/GND holes on the extendershield. The extendershield then already has the traces to bring that power to the Uno.
