Did you post the project in the Gallery ? Do you have a link ?

No, its not in the gallery. I made it 2 years ago for fun, however I did make a short video, I just need to see if I still have it.

Just checked all my thumb drives and external hard drive and I do not have the video anymore, sorry.

You can find Arduino Nanos for very cheap on eBay as well as a simple motor driver and RF modules. I have done that exact same thing myself, and it turned out great.

Im not sure what's wrong with you or your touchscreen but can you post your code and the screen + shields data sheet?
64  Using Arduino / Project Guidance / Re: Bluetooth question on: August 11, 2014, 02:05:05 pm
I have that BT module and it has a pin called STATE, which is directly connected to the on-board led. That led blinks when it is NOT connected/paired, and is solid when it IS connected. The pulses happen every 400 - 500 milliseconds, so if you right a little piece of code that checks if the state is high for longer then that time frame, then you can assume it is connected. Or it could just be experiencing a glitch in which case you should see if it also transitions from high to low after it was declared connected.

Its not hard if you use the millis() function to keep track of the time passed. See the Blink Without Delay example sketch.

I should add, that the pulseIn() function doesn't really work that great for this, so go with the Blink Without Delay example sketch.

If the OP needs a certain bit, then (s)he can just mask off the bit needed. Or use bitRead() (kinda much for something as simple as bit shifting/masking).

The EasyVR cannot do exactly what you want it to do. You want to just talk and have it print what you say on an LCD, but as elac pointed out, it can only have a maximum of 60 words. To do what you want would require a library of at least 100 - 150 words. However if you just keep your sentences very simple you might be able to do it.

Keep in mind, you need to train the easyVR to understand what your saying, it wont be able to by itself like an iPhone or Android phone.

Have you tried the AccelStepper library in the arduino Playground?
MotorControl section

I found this one that you might be able to use.
69  Using Arduino / Programming Questions / Re: TFT TouchScreen V1.0 seeedstudio !!!HELP ME!!! on: August 07, 2014, 03:46:51 pm
The TouchScreenMenu library is old, therefore the contents and other supporting libraries are not going to work. This library is including the TFT library which was changed to use the adafruit ST7735 library. I had to change that on my end, but it most likely will not work for your screen.

What you need to do is contact the original writer of the TouchScreenMenu library and see if there is a newer updated version. I've done what I could but you seem to be having more and more issues every time something is changed.

Attached is the .cpp file, swap it with the one you have now.

you need to find getTSPoint and change them to getPoint.
All getTSPoint need to be changed.
72  Using Arduino / Programming Questions / Re: TFT TouchScreen V1.0 seeedstudio !!!HELP ME!!! on: August 07, 2014, 02:16:06 pm
You did exactly what I was hoping you wouldn't do, which was pressing CTRL-F and replacing Point with TSPoint.  smiley-lol

Its ok, but now you need to find getTSPoint and change them to getPoint.

Did you remember to save it after you made the changes? Once I made the changes it compiled fine.

Attach your .cpp file, i'll take a look at it.
74  Using Arduino / Programming Questions / Re: TFT TouchScreen V1.0 seeedstudio !!!HELP ME!!! on: August 07, 2014, 12:20:23 pm
process is just the function name I want you to find in the .cpp file, in order to change Point to TSPoint.

Thats all. Once you do that, see if it compiles.
75  Using Arduino / Programming Questions / Re: TFT TouchScreen V1.0 seeedstudio !!!HELP ME!!! on: August 07, 2014, 11:51:08 am
Here is an example: There are four in total you need to change, this is just one of them.

Quote
TouchScreenMenuItem *TouchScreenMenu::process(bool waitForItem){
    TouchScreenMenuItem *item = 0;
    do{
        Point p = _controller->getTouchScreen()->getPoint();
   
        if (p.z > _controller->getTouchScreen()->pressureThreshhold) {
            p.x = map(p.x, TS_MINX, TS_MAXX, _controller->getScreenWidth(), 0);
            p.y = map(p.y, TS_MINY, TS_MAXY, _controller->getScreenHeight(), 0);
            item = checkForHit(p.x , p.y);
        }
    }while(item==NULL && waitForItem);
   
    return item;
}

Anything that looks like "Point", you must change to "TSPoint"
