Hello. Me and my friend want to create sort of a complex project. Now we have reached to the point where we must make hundreds of arduinos to transfer a text messages (custom text messages) via IR to a mother-arduino to be displayed on a 16x2 LCD (pager like). We have less to no clue to how an IR system should work in the instance above, which is text transfer.
On the internet we found nothing regarding our issue.
How should the sketch look like, where should we start? We look forward to your answer, thank you.

Starting "complex" is rarely a good idea.
Start simple. Build up to "complex".

Odd that because I put ir communications into google and came up with lots of stuff:-
What on earth were you putting in to get nothing relevant?
Start Simple is right. Here is a debugged project involving the basics. This project works. Build and study this project, get it working. Then use 2 Arduinos, the first receives the command from the Remote Control and then transmits it to the second Arduino. Have the second display the command also.
Then build from there. Take baby steps.
If you are looking for a turnkey solution, I can't find one.
The advice you are getting here is right on. Always start simple. When I get a new kind of sensor I first write as simple a sketch as possible just to be sure I understand the command structure and get a feel for what the sensor can actual deliver to a possible larger project. Maybe the range of the sensor isn't what you require, and it's better to find that out sooner then after building it into a larger more complex and expensive project.

Where can i see something about how to make data transfer via IR using arduino to another arduino?
I can't make baby steps because i have to go big. We've made everything in this big project like easy micro usb connection with easy to configure and install custom software.. except the IR communication system.
@retrolefty my IR sensors have 7m line range, that is enough for me.
Thank you very much for all your replies, i will check everyone's post and attend to every usefull link.
The reason you can't find a project that transfers data via IR is because doing it that way is very difficult. You would send out the data and then wait for a response that the receiver had received it correctly. If it did not, the sender would have to retransmit and wait again for a response. The error checking/handling/logging/recovery and reporting software would be difficult to write and test. That is why this would normally be done via a tried and tested process, i.e. BT or wifi.
Good luck. You will have to recreate or modify a lot of code to do what you want to do with IR.
If you're already using wifi/bluetooth why add another protocol? Surely you could use wifi/BT to send your message? Have you looked at RF links at all?
Seems like you are overly complicating things...
The IrDA standard is defined for IR communications (one of the links I posted). This is designed for transferring data between devices with IR. It was used extensively on PDAs to communicate and pass data around.
It's a project that involves hundreds of cars communicating between them, ONLY via ir.
Who ever specified IR communications for that system was an idiot. There are so many ways that won't work.
I can't make baby steps because i have to go big.
Yes you can, all you need to do is to have a project that just uses IR to communicate. When you have debugged that and got it working then you incorporate it into your big project.
