Where I want to fish is a manmade lake in a valley where the river used to run. I have depth and contour charts and I want to use arduino to slave my Humminbird GPS / Fathometer /Fish Finder to an auto steer system and eventually to an autopilot. Not content with waypoints of lat. long. I would like to take the depth readings to follow the old river channel.
Thus far I have an Arduino Maga 2560, a Uno, an ardupilot, a flux gate magnetometer, breadboards, leds, lcds, headers, relay boards to work with and I have a 12 volt linear actuator to actually steer the outboard.
Now the problem, many years ago ( read that as circa 1974) my first computer was a TI-99/4A and did a lot of programming in basic. I was was also quite comfortable with DOS. Now, at my age I am having problems trying to learn C.
So far I have blinking lights and traffic signals etc runing on Uno. Where I am having a problem is figuring out how to interface several sketches in the IDE and have them compile without trashing each other.
There is a world of info out there and Ii have been combing it for gems. Just one of my hangups is how to enter or change waypoints - without carrying a laptop-
Thanks, I love sparkfun, like a beacon to a new harbour in a storm.
