Robotic Arm (Lilypad powering Servo) Project Help!

Yeah, the lilypad is powering the servo as well.. I'm using a 3.7v battery with the lilypad. I've been trying to use a step up breakout to make the voltage 5v.... yet it is still not working >->.

I'll try giving the servo power from another source and see what that gives me... thanks for the reply!
