I could see it through the plexiglass window on the back of the rov.

So I've got the rov ballasted to float up and drive down so it's usable.
I also got to thinking it would be handy to upload arduino sketches without opening the rov.
I can do it over the rs485 lines but need to trigger a hard reset of the Atmega chip,
I've tried various software methods including watchdog timer triggered by a serial command and using a digital pin to pull reset low but they don't do a full hard reset, the low pulse is not long enough.
resetFunc() is also a soft reset so no use either.
So I'm thinking of using an rf keyfob to trigger it.
