Hi, I have the MAKE: Motor shield, and I'd like to implement a pair of ultrasonic sensors that use a Digital Input, VCC, and GND pins, I was wondering how i'd be able to access the arduino's 5v and GND connection. I'm using a regulated total 14.8 V 12000mAh batteries, and have jumpers with the RC IN and BEC jumpers connected. Just a confused newb here looking for a simple explanation of the pins. Thanks.
