Bad experiences as a beginner

Buy a board (original Arduino !!): Link: Arduino Board Mega 2560

Buy a display (original Arduino !!): Link: Arduino TFT LCD Screen

Take a wiring diagramm (original Arduino !!): Link: Wiring diagram

Take a Software (original Arduino !!): Link: Arduino 1.0.6

Take a example sketch (original Arduino !!): Link: DisplayText or Link: Color Picker

and ?

Nothing works (original certified Arduino rubbish !!) :angry:

Sorry, but if not even work the examples .....

Start here

Nothing works

How I loathe that phrase.

Are you successfully uploading your sketch to the board?

AWOL: Start here How I loathe that phrase.

Yes, obviously his internet works for a start, as well as his whinging circuits. What is more I suspect other things do as well, but what ever problems they have whether related to the Arduino or not, we can't help with out a lot more specific information.

But I behaved. I didn't mention lubrication once!

There is that... ;)

@gj99 I’m sorry to hear that you had a bad experience.

It seems to me that you may have been expecting a bit much of yourself if that is your first attempt at an Arduino project.

While the Arduino system makes it much easier to use a microprocessor it is not as easy as (say) Lego. The whole system is a good deal more complex with greater scope for mistakes that are not immediately obvious. However much we would wish it to be otherwise, it is also possible that there are mistakes in instructions, perhaps because the instructions were not updated when some of the hardware was, or perhaps just because a mistake was not detected.

The reason your project did not work might be because of a fault in the program or a fault in the various connections that you made (due to an error in the instructions or an error you may have made). It is unlikely to be due to an error in the Mega or the display screen.

People here will do their best to help you figure out the problem if you give details of the symptoms.

As a general learning program you should start with your Arduino Mega (without any other parts, for the moment) and try some of the simple example programs that come with the Arduno IDE. As you gain experience you can tackle more complex projects.

…R

I have already experimented a bit with the Arduino: circuits with LEDs, temperature sensors (DS18B20) or relay modules. Everything worked in the end. Now I try the next step with a display. I know that I'm not playing with Lego, but I have to claim that things which a company sells me also work. Everything (hardware / software) is from a single source. And here it is just a board with a display (and 9 wires) - nothing else. I also do not develop, at first I copy only.

This is also my fault: Picture From this thread However, the solution does not fit on a MEGA 2560.

Sorry, it's just annoying that you get today sold so much things that do not work properly.

Post you code and a link to the module.

Edit,

I mean your code not a link th the example code.

Does it compile ? Have you tried the display with nothing else connected ?

Also the specific fault, does it light up at all ?

You may have a faulty module but its more likely a connection problem.

gj99: This is also my fault: Picture From this thread However, the solution does not fit on a MEGA 2560.

The solution mentioned on that thread was to Download 1.5.8 version of the IDE. Have you tried this?

Instead of complaining , why don't you post like almost every other Newbie as follows:

"I have have such and such experience with arduino. I just bought such and such and can't get it to work. Can anybody help me figure out what the problem is ?

Starting you post by trashing arduino products on the Arduino Forum just doesn't seem like the wisest approach.

Let's start with some basic questions:

  1. Have you EVER used an LCD before with the arduino ?
  2. Have you run any basic tests on the Mega to ascertain it's status ? (ie: blink example, digital I/O test sketch etc.) ?
  3. Did you do any research on the TFT BEFORE you bought it ?
  4. Did you post ANY vendor links to where you purchased the products ? (FYI, the term is "Genuine Arduino" , not 'Original arduino' but at this point I suppose that's not important)
  5. Would you like to know HOW to test your Mega ?

More than likely it is a library issue.

  1. Do you know where your Library folder is ?
  2. Do you know where it should be ? (where you should be unzipping your user added libraries ) ?
  3. Have you ever installed a Library before ?
  4. Do you know how to find out the path of your user installed libraries ?

If I posted that I had just bought a DVD player and it didn’t “work properly” what would you be imagining? It wouldn’t play Region 2 disks? It doesn’t connect to my TV? It doesn’t play BluRay disks? The remote’s batteries are flat? The case was dented? The screen showed Chinese text?

Come on, try to be cooperative.

I don't think either of these comments is fair if (as we should) we assume the OP is making a genuine complaint.

If you buy something and it does not do what it is supposed to do you are entitled to return it for a full refund in most civilized jurisdictions.

You should certainly be entitled to a genuine sense of grievance and you should have the right to complain and for your complaint to be listened to.

Just because the Arduino is an Open Source product does NOT entitle it (or us) to ignore normal standards of behaviour.

We have no right to put any obligation on the OP to avail of the extensive assistance that is a normal feature of the Forum.

And we should certainly NOT see our assistance as a satisfactory alternative to a faulty product.

As a matter of curiosity, is there any proper channel for complaints about Arduino products where the complaints are dealt with by Arduino "staff" (or whatever passes for staff).

...R

Of course, but saying:

Nothing works

when the original post mentions a board, and a screen, followed by:

(original certified Arduino rubbish !!)

This is more like just straight insults.

Certainly there are faulty products, and you would be entitled to a refund if they are. But once you get to "user assembled" there would be a few who might wonder if the user assembled it properly.

For example, there was a recent thread where the user just pushed the header pins into a board rather than soldering them, thinking "that would do".

And it took something like a page and a half of questions to even find this had been done.

There was another thread a while back where the user had one of those breadboards where the power and ground lines (the red and blue ones) stopped half-way along, and you had to jumper them if you wanted them to go all the way.

I think it took three or four pages of forum threads, with quite a few insults flying our way, along the lines of "of course I wired it properly you moron" before the user realized it was a wiring fault.

Can you post a photo that proves you have in fact wired it exactly that way? And also post the exact code you used?

Nearly an hour later, I thought this one was rather funnier!

And it is rather farcical for someone to complain that they cannot figure out how to run software.

Yes of course, but it makes no difference :-(

Video of my circuit

The serial port COM12 was not found, try again with a different port?

I would have clicked on ▼ to see what’s available.

You could check Device Manager "Ports (COM & LPT) to see if the Arduino COM port is listed or if it’s even recognized.

More tips here

EDIT:

http://arduino.cc/en/guide/windows#toc4

  • Is the port recognized when the Arduino is connected on its own - no shields or display or external connections - only USB?
  • Have you tried replacing the USB cable?
  • Have you tried using another available USB port on your PC?
  • Have you tried using an external USB hub with it’s DC adapter connected to ensure there is 500mA available?.. no need to answer, just some stuff to try …

So which version of the IDE are you currently using?
