I have a 5 meter fiberglass boat that I've wired all my electronics into but it's not as good as it could be. I have a jre echo sounder, gps, bla bla bla and I don't like it. My thoughts have me scouring YouTube and the internet for an all in 1 unit to replace the big heavy equipment bolted to the cabin roof, I've learnt a tiny bit about the arduino and don't fully understand its capabilities but assume I'm on the right path. I'm wondering if an arduino can be made to display GPS and nmea data like a chart plotter, engine rpm, play music from a smart phone via Bluetooth, switch relays to power an anchor winch, turn on and off lights, touch screen of course. Has anyone attempted or heard of a project like this before or have an idea of where one might start?. I believe this could be a real game changer for anyone with a boat, yacht, PWC or canoe who wants to explore or find a good fishing hole providing they have a 12volt battery. Any advice or help would be helping 100,000 boaties out there wanting an all in 1 reliable unit.
