Communicating With Arduino With Only 2 Wires

[jumbodrawn]

Hi, I am thinking of making a RC submarine based around the Arduino Uno or Leonardo, and I probably won't use a controller, most likely just either a joystick or 4-5 pushbuttons. Ontop of that I want to be able to send video footage back to me, whether it be on a laptop or just a LCD Display, or via a RCA cable. I think I found a good 100meter tether cable that only has 2 wires?

Here is the cable:

Is there anyway I can send so much data with only 2 wires?

 

Thanks alot for the help!

This is the camera: https://www.adafruit.com/products/397?gclid=Cj0KEQiAno60BRDt89rAh7qt-4wBEiQASes2tZ4xNUV6_hCq_piO6R11BAN1ly00XMaJ5SDl1tCJY0saAgsK8P8HAQ

You can use the arduino serial connection over two wires. That would be enough for some basic sensor data and to send your controller commands (via a computer or another arduino in the controller).

 

Video is more difficult. There is lots of data, I've not looked too heavily but iirc arduinos (uno and similar) don't really have the grunt.

 

My solution might be to use something like a raspberry pi zero for the video using a surface bouy antenna, similar to how real submarines used to do comms, for WiFi.

Now looked at that camera.

 

I think you'd struggle to have s single uno deal with it and the commands from the remote just in tend of resources.

 

They seem to have a reasonable baud rate from the camera but if you want video you'd need to look at how high frame rate that gives you for the resolution you want.

 

You also need to consider that unos only have one physical serial connection, software serial works but that will not allow the uno to do other things whilst sending or receiving data. So even receiving an image and sending it on via serial and soft serial will take up most of your process time.
