1  Using Arduino / Displays / Re: Use serial LCD without Tx pin on: Today at 04:24:21 pm
Then what pin I should use. Sorry I am still beginner.

At the internet or arduino?

In order to get any real help here you're going to have to start showing a little initiative and do some searching. I'm feeling a tad generous today so I googled it for you.

Post your code using the code tags (# button in message editor)

Pretty sure you're not properly updating the screen in your code by the sounds of it.

Something like this might be exactly right for your application.

In a nutshell it is an arduino and tiny oled display in one. Add your bluetooth module and you're set.

Typically displays like that are only capable of showing things like the 4 digit time as well as a few other indicators like am/pm, alarm, ect

What sort of voltage are you trying to drive this thing with.

You can sometimes look at most displays at a certain angle and see all of the different characters/symbols they are able to display. Especially those of the proprietary nature as this one is.

And then you probably have to deal with debouncing the button.



What would the purpose of this be? I know the surface level of what debouncing is, but in a case like this, what significance would it be? Just Wondering.

I am not able to add any input for the coding of your project but I stumbled on this thread while lurking with the intentions of learning and liked the idea of what you are working on. I think maybe a cheap lazer pointer wired up instead of the led may be a cool addition in retrospect to the game.
8  Using Arduino / Sensors / Re: safely interface with car sensors. Grounding and voltage (non OBDII) on: March 22, 2011, 04:00:59 pm
Yes, most car sensors are 5v or just a variable resistance reading already.

As long as you have common grounds you should be able to take readings with a microcontroller.

Always check with a DMM first.

This really is basic stuff, the kind you learn from a little effort on your part.

You have given us almost no information whatsoever about what you are trying to accomplish so I am left only assuming your trying to pulse this led to mimic some sort of ir communication device.

Here is an example I quickly found using google (Google should always be your first reference when asking a question)

We talking about a possibility for new software here?

I have been playing with my 20x4 lcd recently as well, i am having a similar issue.

I set up a example (liquid crystal) serial display sketch and when i type out a sentence to try and take up all 4 lines and send it

it will show up in this order.. line 1,3,2,4

I changed the code to say lcd.begin(20, 4);

any tips? thanks.

works fine on 7

Some computers have issues with arduino 0017 and its normally a java problem. Try updating java.
