Homebuilt ROVs Forum

You can power the Arduino with a 12V power source,
From the Arduino website

power supply range is 6V - 20V with suggested 7V - 12V

What the best way to quote the winding wires and what do you suggest with.
Thanks

Hi I tested my ROV in local harbour today, using brushless motors controlled by an Arduino, out of water all working fine. As soon as I put the ROV in the harbour, 3 of the motors switched on to full power I sent signal to turn them off but that didn't work. Does anyone have any ideas at to how to f...

I've implemented your first idea nearly, shore/boat computer - usb extender -- cat 5 - - ROV usb extender - Arduino - ESC to 4 motor + OSD and digital compass computer - CCTV coax and psu for camera - ROV board camera onboard batteries for motors seperate battery for Arduino / osd and digital compas...

you can use adapters, that can transmit the usb data over a cat 5 ethernet cable, up to 150 feet, I've using one at the moment that's 30m, 90 feet.
Adapters are something like $15 off ebay

Hi I'm using Brushless motors. I've read somewhere that the battery to ESC has to be no more than about 20cm. I was planning to use a land based 12v battery down a 30m umbilical to provide motor power, but if this is true I will need to use an onboard battery. What is people's experience with using ...
