You only need to re-route 4 of your existing wires ( 3v7×2 
, servo , and two VCC2); disconnect these 4 wires from the breadboard rail(s), and insert them into a common, previously unoccupied breadboard row. Test everything using a USB connection for Arduino power, and once satisfied that it works, add a separate power source for the Arduino (via the VIN pin or barrel jack).
