Well, I must admit there is not too much for the compiler to verify.

What are you wanting to do, really?
I imagine it would really help you if you wrote a functional description of your project.
What this will look like will be an abstract overview, an objective detailing your desired outcome based on certain criteria, a technical description on how you intend it to function with both hardware and software, and possible consideration for those unlikely but highly probable problems.

A block diagram or flow chart is always a good place to start.

So, just a quick look at your code, some commenting will again always be a very good thing, to help you remember later on but also if you wish for us to understand what it is you are doing in your program.

I have lots of questions or remarks about your code, probably longer than your code in fact.
But why are you bringing in those microphone inputs into your Arduino, I thought they would go to a special voice board you had?

Are you asking for help on your program?

im waiting to get the wifi, bluetooth and voice shields from china when i get the money.
i will ad more comments to the code soon.

i have 255watts of solar panels charging 9 absorbed glass mat batteries

This seems quite unbalanced unless the batteries are small.

OTOH if the 255W keeps up then your batteries are not getting discharged much and that's a good thing.

DOH! i forgot to buy the voltage sensor to read my water level sensor. but i would hate to run a wire thru. i will check ebay for something to read 11V-15V. ironic that i need a sensor to read another sensor, huh?

You cannot "replace" data that's been printed to the serial monitor, characters are printed, the world turns and what's been done cannot be undone.

As the monitor is really just a debugging tool this is not usually a problem. If you really want to do this you need a terminal program that implements control characters (VT100 is the most common IIRC) and then you have to send these control characters to move the cursor back to the home position after (or before) every loop.

Code:

int Light1 = A10; //Will control 1156 Leds inside. or maybe i need digital pin.
int Light2 = A11; //Will control 1156 Leds inside. and might need some relays.
int Light3 = A12; //Will control 1156 Leds inside. oh shit, what did i get myself into?
int Light4 = A13; //Will control 1156 Leds outside.

Are you seriously going to drive 1156 (or is that 4624) LEDs?

you just gave me an idea for a Christmas light display controlled by ........... Arduino!

but seriously i ment to say "1156 LED bulbs".
its the kind of bulbs in your cars turn signal you goofball. lol

[Reply #23 on:]

its the kind of bulbs in your cars turn signal

I drive a 40+ year-old 6x6 Army truck, there is not a single LED in sight of the thing.

If a comment says "1156 Leds" or even "1156 Led bulbs" that means (to me at least) 1156 LEDs, not a single assembly with X number of LEDs.

Remember you are asking for help from engineers or at least people with an engineering mindset, as such when we see a magic number like that we ask if you really intend driving 1156 LEDs. If the comment was "Will control 1000s of Leds inside" or "Will control a shit-load of Leds inside" I may skip over it until you post again asking why your Arduino dies when you turn the LEDs on.

What's the significance of the number 1156?

i googled and i dont know why they picked that number but its the universal part number for a light bulb with off set nipples.

i gotta go clean 16inches of snow off my camper roof before something happens.
or maybe i will invent a robot to do it. he will have windshield wipers as hands.
if i dont post here within a couple days i will probably be dead.

[Reply #27 on:]

aahhhhh, nipples. But seriously heres my updated code. my white led dont light when i speak and my blue and red led does not go off after sticking the sensor in snow. i should probably ask in another thread for help. but they will just say "hey, you just posted that in another thread" lol

Nice to see another person which has the idea to build a camper control panel 
I have just (sort of) finished mine, it's my first Arduino project.
Check it out on:

http://508.winand.nl/?p=1087

(On the right hand side there is a translation option, just hover over the flags, you'll see)
The panel is not build in the camper van yet, which is still under contruction.
I have experimented with a gas sensor to detect gas leaks.
Works well, but the power consumption is arround 100mA, which is too much for my likings
(remember it has to be on all the time..)
I'm thinking of replacing that with measuring the weight of my LPG tank (I use a standing
LPG tank, so putting sensors underneath it should be simple)
