Will do.... thank you..

Thanks guys...

It would need to start on the minute with no more than a couple of seconds off...
I'm in the UK and do have an MSF module so will have a read about that..
I also saw the adverts for the temperature controlled RTC modules which look accurate enough..

Just got to read up on how to get meaningful data from a clock module for this task..

Total noob to all this so some head scratching is called for..

Thanks again
Regards

Hi
I need a timer to operate a relay which will activate a Ham Radio WSPR beacon transmitter.

The requirements are that I need the realay to operate momentarily exactly at the start of every fourth minute
and only on even numbered minutes so, 10:02/10:06/10:10.....etc.

So,just need some start off help with this.
If I add an RTC to my Arduino, can I somehow interrogate the output of that to test for an even mintue and to
test for a 4 minute pass?
Maybe there's a better way to do this....

Thanks for any guidance folks

Paul...
Thanks for that, done as you sugested and put a digitalRead in a while loop
in setup and that works perfectely..

Trying to get my head around this..

I have a loop containing some code to run a stepper motor for a few steps then fire a relay,
then repeat that sequence till I unplug.
It's driving a homebrew macro slide....

What I want is for the software to wait till I've pushed a "start" button before it goes into the loop,
but from then on, to ignore the button...
Question is, do I need two loops?
One for testing the state of the button and the other to run the macro slide...

Very much a newb at this so many apologise for asking what is probably a silly question..

Thanks for any help folks

Thanks for the responses folks, much appreciated as I'm a bit of a noob with this..
All I wanted was to monitor some temperatures and put the results via ethernet but I've got
stuck at base with this very flaky ethernet board.

Like the idea of a seperate router to stick in the sky box...will try that...
Double checked the mac address and that's ok...

Shame really as the ethernet board wasn't cheap... been hunting around the internet and
my problem is quite common...

Anyhoo, sods law, it's been working fine for an hour this morning but not reliable enough generally.....

Thanks again, onwards and upwards smiley

Regards
Philip

Hmmmmm... really frustrating..
Still can't connect using Zoomcats test program...
Well, to be exact, it connects one out of twenty or more tries.
Same with any of the ethernet example sketches...

I know I have a correct and unused ip address and the mac address is right.
Makes no difference weather I use gateway or not.
I can ping the arduino no problems...

Using latest ethernet board with SD card reader.... using Arduino 0022. on Windows 7

My router is a Netgear supplied by Sky boadband.....

99% of time it hangs for some seconds showing connecting then I just get connection failed.....disconnecting..

Would be very grateful for any further suggestions on this, as far as I can see, the ethernet
board is either faulty or it's the router that's not compatible with this stuff...
Can't try another router as the contract stipulates you can only use the broadband suppliers router...

Thanks for any help

Regards Philip

<.................Well what the heck.

It worked once... Then I tried it again and it didn't work. Weird...............>

Same here, wish I could find out why as well....

Connects first time no problems but then it wont connect again either after pushing
reset button or re loading the program...

Zoomkat
Thanks for that test listing

I'm just having a first dip into networking.

Ran your code having put in my Mac and IP and it conected quickly and printed your response...

Odd thing is, if I push reset to run again, it won't connect a second time unless I change my IP to another number  192.168.0. XX
then, it connects but only once...

Will be interested to see how you get on with your board...
I got one yesterday with a temperature/humidity sensor and I'm having a
first time go with it today...

Got the computer talking to it via serial OK but I can't get the time to set.
It accepts the numbers (month day etc) but the clock refuses to start or change time.

Just scratching my head what to do about that >smiley-sad

What you need to do is set your serial monitor baud rate to the same as
the baud rate setup in the sketch listings.

If they aren't the same then your monitor will show garbage text.

Maybe you could use a lower baud rate, not sur really.
If you do alter it in the listings then again match it in the monitor settings.. smiley

Try setting the serial rate on the Arduino serial monitor screen to 57600 baud for the data log sketch
and 19200 if your just using the temperature/humidity sketch

Thanks for that..
I had been looking at the Netduino plus with network and SD card built in
but as you say, it's dot net...

Having looked into it further, there is heaps more infomation and source
for the Arduino + network shield so I think I'll go for that..

Thanks again for the help 8-)

Hi
My granddaughter is about to begin a college course on networking..

She fancied getting to grips with the Arduino gear.

Now, I own an Arduino board and I know there is a network addon for it...

Question is, would I be best getting the addon or should I get her the
latest Netduino board?

Not bothered about cost/value for money, it's a case of which has the
biggest following for her to tap into...

Thanks for any suggestions

Regards
Philip
