I'm wondering if it's something with the easy driver.

I'm wondering if it needs 5V to the lower left corner to drive the logic

yEAH, TURN THE LIGHTS OFF  smiley-razz

nO, ACTUALLY i'M AFRAID i DON'T

EDIT: the above is a good example of typing while the site was all in caps. Sorry about that.

this is a test of...

Code:
what code
{
looks
}
like

edit... well at least that worked.

here is code with some capitals:

Code:
this line is lower case
THIS LINE IS ALL CAPS
THIS is MiXEd

That's NEw... that wasn't what I complained about but it's worse.

.... are crap.

Might just be me but it seems an amateurish mish-mash of sizes and serif / sans-serif.

Yuck.

Compiler's also going to moan about { and } not matching in number, so here's a hint:

Hover mouse over a { or a } and IDE will put a little box round its partner; helps you keep track. When you have the right number of each, hit Control-T and IDE will auto-format your sketch with snazzy indents.

You don't need an Arduino to compile the code remember: you can hit the Verify button instead of the Upload one.

Right now it won't compile since you don't have the servo library sorted, so add this line right at the top:

Code:
#include <Servo.h>

You also left ; off a bunch of lines like this one:

Code:
const int servoPin = 1

And you will also get a compile error based on this:

int buttonState = 0;

... not being the same as:

buttonstate = digitalRead(buttonPin);


Feedback depends on what you expect it to do, in this early stage.That's going to read the button, and then do one "half-sweep" or the other based on the button.

Is that what you want for first time round?

Good start there though. Get that compiled and we can talk more.

Try File, Preferences and uncheck "Use external editor"

I only have a couple of weeks left for this project and that is far too little time to understand the arduino programming code...

No it's not... have a look at these (over and above the very simple stuff on the examples page)

Counting button pushes
Random numbers
Servos

If someone could .... program it for me, that would be great!

Yes, it would, but I doubt it will happen, for a variety of reasons.

But loads of folk will help when you show what you tried and got stuck on.
55  Using Arduino / Project Guidance / Re: BYTE keyword error on: February 17, 2014, 04:23:24 am
In the OP's defence, I don't see an occurrence of  "BYTE" in that code.... but I suppose it could be in one of these?

Code:
#include <string.h>
 #include <ctype.h>

EDIT.... wait I found it with my other glasses on

Post your code in code tags.... didn't you see half of it's in italics? Somewhere in there there's a square bracket i square bracket from an array and that turns italics on. So the square bracket i square bracket has actually gone missing.

Select your code and hit the # icon above the  smiley-sweat

Search the forum and Good-old-Google for "beacons" and "beaconing".... I have no experience of them but I think they are devices that let robots latch on to each other, so no reason why the human couldn't have one? I think they're IR.

Your method doesn't actually detect that the pump is running though: just that it's likely to have power to it.

The transisitor? You sure it's ok? Connected the right way round?

i need the code for two motors,i tried to double the code but it not works,what do I do now?

I think you post the code to show what you tried, and explain what didn't work.
