Series

Parallel

-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

Another pre-activity

Trying “wiring” your control box using string

Stripping Wires

Wiring Reminders

Use strippers for stripping plastic

and exposing the wire as indicated

in the essentials presentation.


Crimping

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.

  • 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

Then the black…

  • Once you have crimped together both your black and red wires you can attach the spades to the contacts.

Then 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

Wiring the Control Box

  • 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.
