I`m building an ROV sub, and as i am an Arduino noob and need help writing some code.
the 6 rov motors are currently controlled with on and off switches in an arcade joystick, and relays.
I want to reduce the number of cables, an im hoping to use the rx/tx on the arduino. I will have one arduino on the surface and one in the water.
can someone please help me getting started with a simple code that I can build upon?
" push a button connected to the surface ardunio , and make the other arduni write a pin high"
im sure it is super simple. (not for me) :P
thanks from Norway. :D
