Boo...  at that price... this isn't even slightly geared towards hobbyists.

RGB LED's are really not that expensive.  $0.99 each is really not that bad.  http://www.mpja.com/prodinfo.asp?number=17137+OP

If you have some basic parts, there are transistor equivalents to the MAX232, you can find examples at SPARKFUN as well.

I can't help feeling this is going to be sort of messy.

Good luck.

Brett, ZeroVector ... You  guys rock!

ZV, The Timer Library you used was the answer I'd been searching for.   I had no clue about it and it allowed me to have much better control over my Kiln temperature with correct PWM output settings.

I use an SSR to control a 2000 Degree F, 20 Amp Kiln.  I have now been able to reach my goal of 1290F and was hovering between +/- 6 degrees with minimal overshoot.  I was thrilled!

Setting PID values correctly is truly an art/science that does seem to get the experts some nice paychecks...

Your application seems more like an ON OFF design from what I can tell... the PID library works best if the feedback about what you are trying to measure/control is changing as it get close to set point.  Like a temperature reading, for example.

A PID tries to adjust it's output based on the input error...   but in your case... it sort of like playing 1...2...3... RED LIGHT!  if you have ever played that game... you might know what I mean...

You have an action with inertia... water feed.... and you want it to stop at an instant in time with little warning...  which sounds pretty hard to do to me...

I'm not claiming to be a PID expert though... maybe I can be corrected by one of the guru's here...

Please consider keeping PID Library an active project.  I personally love it.

1332  Forum 2005-2010 (read only) / News / Re: How can I send a float variable to Processing? on: July 03, 2009, 05:59:01 am
Prior to recent ARDUINO versions (version 15 I think) I was using the following subroutine to print floats.

Code:
//--------------------------------------------------------------------
void serialPrintFloat( float f){
//--------------------------------------------------------------------  
// print results properly with float decimal value
 int i;
   Serial.print((int)f);
   Serial.print(".");
    i = (f - (int)f) * 100;
   Serial.print( abs(i) );
}


Now lets hope this question thread can me moved to where it belongs?

I am trying to do this without a crystal...

All of the bootloader, UART and sketch code timing is based on a known crystal speed, that's why a 16MHZ crystal is specified.  Get a 16MHZ crystal and try again.

Unless you have edited an recompiled a new bootloader, your choices for  "F_CPU" are 8 and 16 MHZ.

Well, you don't actually have to have them installed.

Yeah, I mean I understand your intentions here, but maybe the word "MUST" could be replaced with "should".  My testing shows that there are no real dependencies other than the need to have access to AVRDUDE.

Program RUNS with no complaints on a system without AVRstudio and WINavr, but that does limit its usefulness, of course.

Looks real nice, btw.

I did notice that it does not show up in "start" menu... that would be nice to have.

Secondly, the EXE does seem to be lacking a ICON in the Program Files directory... but it's there if I create a shortcut.

You did mention that a sample hex was included... but actually, I didn't see it.


After successfully locating the arduino and finding a random hexfile, I did get the not insync message...  it was just the one line and "done".

Code:
Started avrdude.  Please stand by..
avrdude.exe: stk500_getsync(): not in sync: resp=0xe0

avrdude.exe done.  Thank you.

Not actually checked what it *did* yet...

I think it's just saying that my COM port was found, but my settings are wrong for the particular Arduino I have.  (Boarduino USB  with a 168 installed.)

After that, I pressed HELP  (yeah, should have done that first, I suppose).. I got this when I pressed help:

Code:

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.




NOTE: HELP *WORKS* until I try to SCAN and UPLOAD... after that... it does not work until I close the program and restart it.

Dunno if this is helping.

My system is XP SP3.

I will check it out too.  I still still do a lot of work with AVRGCC so this might be fun to mess with.

(I know the average AVRFREAKS and geeks seem to  dislike the concept of an avrdude gui... but I always thought it would be nice to have)
