hey

if you take it slow it will be easy...

- do the button tutorial; this gets buttons working
- do the serial tutorial, sending a sting to request the ask to do something simple
- join the button code to the serial code
- find the serial code that will recognize responses from the device, if necessary.

Once you have one button sending one control code that does something, everything else will be easy.
If you don't need to read the device's response to commands, this will be especially an easy project.
With serial comms, the best thing to do is to build incrementally- - make sure one thing works, before you add another.

True... unfortunately, I do need it to listen for the response, which should read "OK" or "ERR" (whatever). (in which case I want it to light up the Error LED.

Hence why this is above my current level of skill...

I'm a good builder, but I *suck* at programming.

Here's the challenge. (I'd even be willing to throw some dubloons at whoever can find me the most complete solution.)

I've so far used such things as SimpleMessageSystem, and some random software that ran encased on the arduino. The challenge here today is to take that up a notch.

I need the Arduino + some hardware (pots, buttons, etc...) to become a hardware controller for a serial device.

Firstly, is that possible?
(if yes)
Secondly, here is the device http://www.birger.com/Merchant2/merchant.mvc?Screen=ef232_home (it's 900$) :-(
(if still interested)
Thirdly, here is the syntax and response that the device uses: http://www.birger.com/Merchant2/merchant.mvc?Screen=ef232_softintf

What I would like:
An "OK" led (green)
A "Communicating" LED (orange)
An "Error" LED (red)

A button to go to near focus.
A button to go to infinity focus.
An encoder/pot to control the focus.

A button to open the aperture one stop.
A button to go to wide open aperture (or hold the "open one stop" button for 3-4 seconds or something)

A button to close the aperture.
A button to go to closed aperture (or hold the "close one stop" button for 3-4 seconds)

Thoughts?

Alas, no :-(

The code's applied, but I need to figgure out how to read the new pins.

*cough*

I applied this code...

Stupid keyboard.

Hey, I still haven't gotten the extra pins to work...

I applied this code to my pins.c file, and successfully uploaded it to the arduino, but still haven't been able to get the arduino to export the extra data.

I added two extra "i's" to the object that splits out the data into all the ports, but it doesn't add anything.

I was thinking... do you want to try running an output over the internet, into your copy of max? (using net.write or whatever the 'net series of patches are called?)

"extra" analog ports? Do you mean the PWM outputs?


OK-- I get it. You mean AD6 and AD7 on the Atmeg168? I don't have one, so you will have to fiddle and let us know what the answer is.

You're the guy that wrote Arduino2Max? Man, dude, you rock.

Where are you located? If I lend you one of the arduino mini's, can you figgure out how to read the extra pins? I'm gonna need them for my project.

Man, I wish I had these!

My Xbees haven't ever talked properly together, so the 2 shields that I purchased from you are still sitting on my shelf because I can't get them to work :-(

I've been browsing around for examples of people successfully recieving DMX (Digital MultipleX signal (RS485 I believe).

http://en.wikipedia.org/wiki/DMX512-A ... for anyone who's unfamiliar.

I know there was a lot of work put into outputting DMX, which has been achieved through the DMX shield.

(http://www.arduino.cc/playground/DMX/Opendmx)

Anyone?

I'm willing to start working on it, but I don't want to start from scratch if anyone's already tried... (i'm game to working with someone on already pre-existing code to see if we can make it work.

Thanks!

...or even better, just get a speed controller for R/C and plug it into the arduino. The ESC (Speed controller) itself is an h-bridge, has reversing, etc... and is MEANT for this.

No?

Yes, but does the Arduino Mini convert 9v > 5v inside of it for use on sensors & digital pins? I was looking at the schematic and there's something that does some kind of conversion in the top left of that PDF of the schematics.

The USB board is the USB stamp that is used to interface the mini to a computer.

Nono, what i'm trying to do is...

---------------------------------------------------------
USB Board

  |   |     TX/RX wires

Arduino=======9v
  
   |+5v|

Sensors & other things that need +5v
---------------------------------------------------------


Which pins will DELIVER +5v OUT if I put +9v IN onto the arduino?

USB works, only if you connect the USB power as well. Weird?

NVM. Found it. +9v to Pin 20, -ve to Pin 19. +5v comes from Pin 17, and the ground for the 5v line comes from Pin 3.

PROBLEM:

Why won't the USB work?

What's the correct way to wire up a 9v circuit IN to the Arduino mini to power it, and a 5v circuit out to power sensors, accessories, etc...?

Soundlight... Which company is that again? That's not a rebranded "sunlite" by nicolaudie, is it?
