    Hi all

    I have spent the last few months coming to grips with ‘Arduino.’ This is a whole new world for me and it will transform how my model sub works! The system is yet to be wired in so there is a long way to go but here is a little vid showing how it all works. So any comments are welcome, and I will update you on how it goes in practice.

    Hi John,

    Happy New Year! (Glad to see that you are putting empty wine bottles to good use!)

    That looks very promising. I particulary like the ability to program functions together in a sequence.

    One slight reservation - you are putting all your eggs in one (Arduino) basket. You need to be sure that the Arduino can cope with interference, varying battery voltages, brown-outs, surges etc. I am advised that wafting a hair dryer near the receiver is a good test for interference. (Wish I needed one!)

    But it looks very good and it is all small and cheap enough and well supported.

    Looking forward to the next phase!

    Thanks for that. I agree about the interference. I have already found a glitch. i took the system to the local 'club' and had it in the car. The sealed container for th epressure gauge became warm and the surface routine therefore was stuffed. I need to add another hose to it to equalise depending on temp. This is just the first of probably a few issues. i will try the hair dryer. Sounds rather scary!

    HI JOHN ,

    I'm waiting with great interest what have You don .
    Do You have some news about Your work ?.
    Can You add a small example of Arduiono code here ?.

    I'm starting to learn , with the small steps the Arduino secrets , but there is a Huge amount of information to ketch up so is going to take some time .
    Please give us some update about Your progress .

    All the Best

    MARIUS

    P.S   https://www.youtube.com/watch?v=rJKeSVkz0sY&feature=youtu.be .... these was my first attempt with Arduino .

    I am about to start to rewire the sub as I had another project to finish First. Happy to post some code. What do you want?

    My project is these :

    http://www.theassociationofmodelsubmariners.com/t1296-los-angeles-build-logs ,

    and I need some code only to control the Ballast pump .
    I'm interested too about Fail Safe Code , same as Yours . In case of Missing Rx Signal for 3 second to blow the water out of the Ballast Tank .
    But I want to LEARN from that Example of Yours , to develop some different Commands .
    If is necessary to "translate" that Arduino commands to an ANY "C" language I'm screwed !!!.
    I DON"T KNOW ANYTHING about other Programing Languages .

    And above all , How You did manage to transform that Code You Wrought on Arduiono into Electrical impulse for the Relays and Pump / Motors / servos , ETC ?.
