Topic: Help with parallax serial LCD and arduino uno (Read 9077 times) previous topic - next topic


this is like twice in as many days that the LCD/Display area has been ... ah ... "flummoxed?"
now I have to add Displays to the banned list of topics at Christmas dinner (Politics and Religion being the others)   :D


Boy am I glad I was away from my computer all day - especially since it seems that my response to the OP helped set this all off.



I think maybe a "sticky" with suggesting posting the sketch and part PDFs and/or links may be very helpful now. (maybe even needed)

I have to say if I was the OP, I would have been a little surprised if the first two responses to my post were some clown telling me what a bad mistake I'd made and that I'd paid four times too much followed by someone hawking his own products and telling me I'd made a poor decision because I hadn't purchased his goods. I think OP might be fair concluding that this is a pretty rough crowd. Some people are okay with that kind of razzing but I think it's fair to suggest that experienced forum members have just as much obligation to respect the feelings of new members as new members have to learn the forum rules for posting.

I am not surprised by you that you cross your own line of respecting other by calling me a clown. Certain members like you are not to be taken seriously.

liudr, reread my comment. You will see that I called NickPyner a clown, not you.


Will you support a sticky with some basic requirements for posting, such as pictures, code, link to hardware data sheets?

I think that's a good idea.

I would have been a little surprised if the first two responses to my post ...

The thing is, and beginners don't necessarily know this, and we try to be nice to them, I hope, that anyone who joins a forum has a duty of courtesy to not ask questions without doing at least some research, and preferably referring to it. Otherwise they are just asking us to do for them, something they could have done themselves, in five minutes.

Now since the original post was about wanting to connect a parallax LCD to an Arduino, I googled:

Code: [Select]

parallax serial LCD +arduino

First response:


(Getting started with Parallax with a link to Arduino code). It contained this sentence: " Please see our new KickStart pages at the Parallax Learning Center:2x16 Serial LCD Backlit.".

That leads to:


A very detailed page, showing exactly how to wire it up to various devices including an Arduino.

Considering that the answer to his question was hardly obscure, I think a reasonable response to the original post would have been:


You may think (as Mr Koala no doubt does) that this is unhelpful. But really, going to a forum and posting a question, when the answer is readily available, is an abuse of the time of the volunteers who spend a lot of their time, for no payment, in trying to answer questions.

The OP has not responded since the first post, and this thread is going downhill somewhat. I am locking it now.

If the OP wants his question answered please refer to the links directly above.

Thank you.

The forum user TinselKoala has posted a number of insulting comments about this forum on his YouTube channel. He now says:

The trolls and stalkers have made me decide to remove my Arduino videos from public view.

That is his prerogative, of course, but in case anyone is wondering if I am abusing my powers as moderator:

  • I have not posted any comments at all on his YouTube channel.

  • I have not voted up or down any of his videos.

  • I have not suggested to anyone else that they do either of the above.

  • I have no knowledge of who is doing that to his channel (if indeed anyone is).

  • My moderation in this thread was in response to his insulting of the entire forum in his first post. That is what moderators are for - to keep things polite.

  • The initial question about soldering was made by the original poster (gretsaw908).

  • One single person responded that the OP would have to do "more soldering". However that poster only currently has 150 posts. Hardly one of the more experienced posters, and certainly not a moderator.

The original question was how to connect a Parallax LCD to a solderless breadboard. Surely that must be obvious? With hook-up wire? As I pointed out in subsequent replies if the OP had Googled it he would have found out for himself very easily.

The other moderators and myself are looking on in disbelief that this has escalated to the point where TinselKoala has taken down his YouTube videos, in response, apparently, to the contents of this thread.

Visitors from YouTube: judge for yourself whether this is an over-reaction.

We spend hours here helping poster after poster with their questions about the Arduino platform. Many people comment that this is the most helpful community they have come across on the Internet. Many people comment how surprised they are that questions are answered so quickly, so competently, and so completely.

We have better things to do with our time than to stalk people on YouTube. Honestly.

We've just had our FIRST "report to moderator" email about this thread from a forum member.
It is in support of Nick.

Please understand, prior to this, we received no emails generated about this thread - no complaints about poor moderation, no comments about the quality of the early responses to the OP.

We're moderators, if someone complains, we do our best to respond and correct.
We cannot possibly read all of the hundreds of posts every day here, so we rely on members to report matters of concern in their areas of interest.
This isn't a minor channel with a few tens of views over many months.
We don't expect to get it right all of the time, but neither do we expect to be slandered/libelled over matters that have not attracted any reports.

We do our very best not to censor, and only edit posts to make them clearer or more accessible, or in very rare cases, to remove offensive material.

We also don''t have access to all the hardware one could possibly attach to an Arduino.

Do not send technical questions via personal messaging - they will be ignored.
I speak for myself, not Arduino.
