A few years ago I remember someone created a chart (Massimo pointed it out at a workshop I think) detailing where all the components of the Arduino were sourced from as part of carbon footprint exercise - can anyone remember where it is? As i've been googling for a while now and can't find it.

I may be missing something here, but it doesn't seem to be possible to have 2 (or more) sketches open at the same time with the Arduino software, this would be very handy indeed.

Blimey - that did take a long time for a reply!!!

Thanks for the response.


I did manage to achieve it in the end, though not very elegantly as I was right up against the wall on a deadline.... It did the job though;)

Hi,
Can arduino cope with reading & sending data every 100ms between boards?

I've a project which involves 2 boards sending data to each other over serial, where their serial connections can be unconnected or connected at any time. The code works brilliantly if one is just sending data to the other (read every 10ms, send every 20ms), but they need to send data both ways & they tend to freeze if both are setup to send & receive at the same time. I have tried limiting the sending of data to once every 1000ms but they still freeze up.... Any ideas why this is happening & what I can do to avoid this? I can post code if required.

Thanks for any help
Tom

edit: I suppose this question boils down to: is this theoretically possible? & if so what's the best way to tackle it?

@Conrad
So you've managed proper serial communication without jail-breaking?? !!

Ah just found a post & some comments linking to the original project:

I'm looking to make this:


For smoothing a sinwave as per this project:

I'm checking if I'm about to get the correct inductor
as i've never used them before, in whcih case would this one be OK:

Thankyou clever people.

got the WebClient working:)
Cheers asz it was one of your tips that solved it:

2) Connected another mac to my machine via ethernet and looked up what ip it was getting.

I unplugged the other mac & typed the same IP address that the mac was assigned {192,168,5,2}

So what confused me is that one IP address can work for the webServer but not for the webClient example. But the IP I identified above (using another machine) works for both examples.

Very happy now:)!

I got the webServer example working after a bit of help
( http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1236113841/5#5 )

But now am having trouble with the webClient example which doesn't connect at all.

I used the same IP address (byte ip[] = {169, 254, 70, 27 }smiley-wink that works with the webServer example & I'm able to ping the shield. Any tips?

I'm a bit bemused by wireshark in terms of trying to track down the issue, any tips with regards to that (or other software to track down the problem) would be gratefully received.

Oh yes, I'm on OSx arduino 13.

Ta Tom:)

I didn't manage to get that schematic to work in the end - I was on a deadline so ended up switching two power supplies - really inefficient I know, but time beckoned. Can anybody else shed some light as to why the schematic didn't work?

any help?

Here's the circuit doesn't work that switches both EL's when I want it to switch them individually....

14  Forum 2005-2010 (read only) / Interfacing / Re: Switching el wire from Arduino on: March 23, 2009, 09:53:40 am
And here's a circuit (that works) where a single wire switches on/off. The two green wires coming in from the right hand side are the AC power supply. The black cables feed the EL wire.


ABOUT TO ADD DOUBLE SWITCH IMAGE
15  Forum 2005-2010 (read only) / Interfacing / Re: Switching el wire from Arduino on: March 23, 2009, 08:41:04 am
I'm also using EL wire & was wanting to individually switch multiple wires powered from a single power source.

I've got a some moc3041's and have wired one up so a single wire is switched, however, when I try to add multiple moc3041's in order to switch more wires, all the ELwires go on/off rather than individual ones....

can somebody give any tips? point to a schematic?
I'll post a pic in a second.

Cheers!
