I don't know if its me, that I'm new to boating, my age or a general thing but when out on the water I can never remember how many blasts of the horn mean what.
Not that I have ever heard anyone else in my few months of boating using theirs either so I'm not sure how usefull this little device would be. Your comments are very welcome!
If anyone is interested in this and would like the code (which is very simple) and the circuit diagram let me know.
So back at home I started playing around with an Arduino (well a breadboard version as I'm a cheap skate)to while away the hours until I can get the boat down the Nene.
I was looking for ideas and suddenly thought of a Horn Blaster!
So after writing the code and programing the Arduino it works (In Theory as not connected in the boat yet).
7 Buttons, one Relay board and a small Speaker is all that is needed (other than the Arduino)
The Relay board would be connected to the Horn Switch and the control box could be placed in an easy to reach location. These units use very little power as they can be powered by USB so less than 500mA. A 9V battery or 4 AA would power this for a long time if you didn't want to connect it to your 12v supply.
There are Seven Buttons
1 - Going to the Right
2 - Going to the Left
3 - I'm Stopping or going Backwards
4 - Turing Round to the Right
5 - Turning Round to the Left
6 - I Can't Manoeuvre
7 - Manual
