blink without delay to flash your on-board led...

Yes, you need to look at this. The problem is, I think, that you press the IR remote when a delay is running and it is not received successfully.

(I'm travelling.. will try to help more Tuesday...)

Dizzwold, I have a preliminary version of the nRF24L01 example I mentioned earlier, here:
http://arduino-info.wikispaces.com/RadioLink-Joystick-To-Servos

This is NOT just what you need, but it is an example of sending real-time data over the radio link.

My Grandson Noah wrote this, and I 'cleaned up' the examples to make it clear what is happening. I HOPE..   Perhaps the organization of the code examples would help you keep the complexity organized. I know I go crazy unless I do this. But that might be that I'm over 40. Also 50, 60, and 70  smiley

This uses the RadioHead library. Noah found the "ReliableDatagram" capability worked best.

Any comments/critique/suggestions would be appreciated.

dizzwold, you have an ambitious project here and it's easy to get confused.

I suggest you back up a little, and get one part working at a time.  Maybe just the GPS first, and make sure you understand how to format the received data into the form you will need for the radio transmission.  Maybe then just the radios, with "fake" data of the correct format.  Divide and conquer. Write small test programs, then combine them (carefully).   

You haven't given up yet, so that proves you have persistence.. the most important Engineering quality.

Sorry I can't give much help/examples right now. I will have an example using  RAdioHead library (A follow-on to the RF24, I believe.)  One of my Grandsons has a working example with one arduino/radio having a joystick and the receiving arduino/radio having two servos in a pan-tilt arrangement, pointing a small laser around in response to the remote joystick.  It took him a while to get the data formatting and scaling right.  But he had patience, and I only helped when he asked. I'll try to get that up on the Arduino.Info site in a day or two.

Keep on keeping on!

Hi,
After the volume of problems with the controller-based USB interfaces on Arduino I stuck with FTDI on my latest version (Like THIS: but R3 pinout)

Sparkfun's new RedBoard  HERE: has also gone back to FTDI.

KISS

YMMV

Hi Elliot,

THANKS! I was afraid of that...  Skool IT seems universally fearful. Wish we could get a couple of testimonials from big school IT that "Arduino FTDI Drivers are No Problem"..   Anyone have suggestions?

I have this on the ArduinoInfo.Info site:
---------------------( COPY )---------------------
WINDOWS XP - 7 - 8 INSTALL PROBLEMS:

Windows 7 / 8 may not see the Yourduino or Arduino board when you first plug it in.

You must install the USB serial port drivers. Download and install the Virtual COM Port Driver from this web site: http://www.ftdichip.com/Drivers/VCP.htm

The easiest way may be to get their Setup executable that can load the drivers here:
http://www.ftdichip.com/Drivers/CDM/CDM%20v2.10.00%20WHQL%20Certified.exe
This is an executable program that loads the drivers. It SHOULD work for Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2 and Windows 8/8.1.

You can check that the drivers have been installed. Plug in your Arduino/Yourduino and then open the Windows Device Manager (Control Panel > All Control Panel Items > Device Manager). Look for a "USB Serial Port" in the Ports section; that's the Arduino board.
-----------------( END COPY )----------------------

I assume that Setup executive will also ask for Admin permission. Can any test on a WIN7 WIN8 machine>

At least the "WHQL%20Certified" title may relieve School IT Anxiety a little??

Hmmm. Latest look at Arduino Downloads:
---------------------( COPY )---------------------
Arduino 1.5.6-r2 (release notes):
Windows Installer, Windows ZIP file (for non-administrator install)
-----------------( END COPY )----------------------

IsThere a specific "non-administrator install" procedure??

Thanks!

Hi,
Need much more detail.

What kind of objects? What material?

What is "long"??

And what are you trying to accomplish??

9  Using Arduino / Programming Questions / Re: Bistable button? on: June 25, 2014, 11:25:56 am
This has been a great discussion about coding standards and styles etc.

I have been doing 'technology' for 60 years and love Arduino.

But there is a simple solution to what you want: It's called a "Toggle Switch".

Hi Steve,

I don't have this hardware set up, but I also get a compile error at
Code:
  // Setup time
  tmElements_t tm;

The libraries are found.. What RTC library from where are you using?
11  Using Arduino / Project Guidance / Re: Alarm system project help on: June 18, 2014, 09:15:03 am
Hi,

It would look something like
Code:
if (temperatureC > 30.0)  // Note the 30.0 is now float also

Does your code / hardware work just writing to the serial monitor?

Hi, Installing libraries: There is a new easier way with the latest Arduino IDE Versions. Just see  THIS:
13  Using Arduino / Project Guidance / Re: Mega + external "independant" power supply problem on: June 18, 2014, 08:33:55 am
Hello Ded,
Quote
the config on my last picture is correct ???

That looks right.. The Mega only "needs" 9V, but the 12V should be fine. In your configuration there is very little current coming from the onboard 5V regulator on the Mega.

I will look closely at the physical clearance between the Mega and the Mega Sensor Shield and put some warning on my sites.

Other Thing: You might try, just as experiment: If you apply 5V on a "dead" mega from GND-5V does it light up at all?

Il est temps pour une bonne chance avec votre projet!
14  Using Arduino / Project Guidance / Re: General strategy for using the ATMega328 on: June 17, 2014, 08:49:51 pm
Hi,
Really a personal decision.

IF you need absolute lowest cost and are making a number of the same thing, you MAY be able to save by using the plain 328 chip plus crystal, capacitors and a resistor. Then  you need a separate USB-serial programming adapter.

Or get a Pro Mini copy for $6 like  THIS:

If you want easy USB programming but small size try a Nano copy like  THIS:

But at $16 for full featured Arduino Derivative boards like  THIS: you may find that a better approach.

See:  THIS: about "Connecting Stuff".

DISCLAIMER: Mentioned stuff from my own shop... but these type boards are widely available on Ebay, Amazon , Sparkfun etc.

15  Using Arduino / Project Guidance / Re: Mega + external "independant" power supply problem on: June 17, 2014, 08:39:44 pm
OUCH!

What is happening here??? Let's try to figure this out. 

Are both Mega's definitely dead?  If you plug them with USB only to your computer can you upload BLINK?  Does the PWR LED come on?  Does the PIN13 LED blink at ALL?

If you have a Mega that will load BLINK from USB, can you disconnect it, plug on the Sensor Shield with NOTHING connected to it. Then plug USB back in. Does that work?? 

Need to divide and conquer this problem.

Where are you located? Maybe I can get another sensor shield to you..

Sorry for the problems; sometimes these things can be very frustratring.

Let us know...
