Step 5

• Find the electronics plate, your servo 
• If you purchased a complete kit with an Arduino Nano and Undershield, install the (3) 10mm stand-offs. These should be installed with nuts on the underside of the plexiglass plate and the end with screws, going up.
• If you are using a different brain (not the Nano) you will need to place your micro controller board on top of the plate and find the mounting holes that line up. If you are using stand-offs or spacers that will need to be attached via the underside of the plate, attach them now.
• Install the servo with the shaft positioned so it is centered and screw it down with (2) 2-56 x 3/8 screws. Route the wire through the center hole
• Prepare your switch plate. Install the 2 switches (if you want to switch the data power and motor power individually) and solder a short piece of wire between them. 
• Prepare the battery pack. Find the (2) 2-pin leads and connect the 2 black wires to the black wire coming out of the battery pack --solder it and tape or shrink tube it. The red wire from the battery pack and the (2) red wires from the leads will be left disconnected for now, until we install the battery holder.
• Install the battery pack to the underside of the top deck (not the electronics deck) using the (2) 2-56 x 1/4" flat-head screws (they are the black ones)
• Run the battery pack wires up through the hole in the deck
• Place the switch plate's tabs into the 3 socket holes toward the back of the plate
• Finish up your soldering. The red wire from the battery gets soldered to the first switch and also to the jumper going to the second switch. (This will send power to both switches)
• Solder the last 2 red wires (from the 2-pin leads) to the 2 switches. (This will send power to the micro controller and motors as each switch is clicked)
• Place the electronics plate (running all the wires through the center hole) on the bottom assembly and attach it to the stand-offs
