Wiring the Control Box
-Current has 1 path-Voltage is divided up to each resistor-Current is the same through each resistor
-Current breaks up along multiple paths-Voltage across each resistor is the same-Current is divided up to the resistors

Stripping Wires
Trying “wiring” your control box using string
Wiring the Control Box:Another pre-activity
Stripping Wires
Use strippers for stripping plasticand exposing the wire as indicatedin the essentials presentation.
Wiring Reminders
Crimping
• Once the wire is firmly crimped, secure with electrical tape.
• 8 spades are needed to connect your red wires (same for the black set)
• To crimp the wires line them up next to each other and gently twist into metal ring until you can see both wires at other end.
• Use the crimping part of your red wire cutter/crimper.
• Make sure that you squeeze the metal ring and not just the plastic.
Wiring Reminders
Wiring the Control BoxStart with the Red Wire
• Measure distance between contacts.• Cut 8 red wires and 8 black wires.• Wire 1 has to be long enough to go through
control box to the battery

Wiring the Control BoxThen the black…
• Once you have crimped together both your black and red wires you can attach the spades to the contacts.
Wiring the Control BoxThen the motors…
• Attaching the propellers• Use 8 of the blue spades • Use the same stripping and
crimping technique• Note which color wires go to
each switch/propeller

• Control Box Helpful Tips:– Label the switches (inside and outside the box)
as up/down, right, and left– Write down which color wires connect to which
motor on the ROV– Connect all the wires together to the spades first,
then plug the spades into the switches– Draw a diagram of which color wires connect
where on the switches. If anything falls out, then it can easily be reconnected.
– If a motor is turning the opposite direction desired, swap the 2 colored wires to opposite sides.
