For real green horns

Hi. I am new to electronics, I mean green and spanking new. I purchased a Parallax 2-axis joy stick with breadboard and am lost on how to wire it to control two 12VDC motors on a marine ROV. Can anyone help? It is P/N 27800.
Thanks

    More info please.

    Did you check the product page for the documentation?

    If I were you, I would probably study the Digital I/O Board Kit.

    I'm not sure if you would want 12 volts going through a two axis joy stick because you are around water and could get electricuted·and I'm not really sure if that part should handle 12 volts.· It should probably be optically isolated.· I'm also thinking that you would want to have a heat sink to protect you from any heat the project makes.

    We're not allowed to make modifications to some of the power equipment at work.· If we do, the manufacturer is not responsible.· In my judgment, it should probably be·overseen by a licensed electrician.

    ROV is Remote Operated Vehicle correct?

    So the question is... Would this joy stick be on say a boat? And the ROV in the water? And the two 12 volt DC motors would be on the ROV?

    And if this were the case, would there be wires going from the boat to the ROV? Or would this need to be wireless?

    Basically I would use the joystick as an input to a "microcontroller" (computer sold here), then use some sort of output to a motor controller of some sort.

    And note there are different types of motors which would be controlled differently. One type is just a regular DC electric motor which can run forward or backwards. Another type is called a stepper motor or servo motor. These would be controlled differently depending on the type of motor. And robots have these motors in them (both types). Some small play robots can be controlled by wireless devices remotely. And with a joystick!

    Also the microcontrollers (computer chips) are different. Some are faster. Some can do several things at the same time. Some are very basic and also very easy for beginners to program. Might want to get a "What is a Microcontroller?" kit which is not very expensive, then this would teach you the basics of writing programs to control things. This would also teach you the basics of wiring.

    Then you could see where something like a switch or a joystick could be used with the help of a microcontroller to control something like a motor.
