Hello guys ! I have this hydroponics project and I would like to build this underwater probe. I would like some suggestions, please. The most important thing is that is has to be arduino based. Second, I have to transmit both power and data with the same cable. On one end of the cable should have the arduino and 12v power supply, at the other end it will be the camera, the h bridge and 2 dc motor. What sort of cable should I use ?
