Multiple Arduino's communication to PC (VB.net) using Ethernet (UDP)

Using Arduino Programming Questions
#1

I want to receive data from multiple Arduino's (max. 4) in a VB.net application running on a PC. The distance between the Arduino's and the PC is about 100ft. Only once or twice a minute a numeric value must be send from a Arduino to the PC.

The best way to do this, in my opinion, is to do this through ethernet communication. I'm thinking about using UDP.

Question: is it wise to use UDP for this? If yes, does anyone has experience with some kind of "system" and is there sample code available?

Many thanks in advance.

I think so, especially if the devices are all on the same localnet. I don't have the VB.net code. I use Linux and C on the PC.

You might consider just using serial communication instead of ethernet communication.

zoomkat: You might consider just using serial communication instead of ethernet communication.

I was considering RS-485 but I think I'm more flexible when using ethernet

#5

I'm looking for some VB.net and Arduino sample code.

Is there anyone who has experience with some kind of "system"?

#6

I'm looking for some...Arduino sample code.

The Ethernet library comes with sample code using UDP.

This is not the VB.net forum.

Have you had any luck with this? I am currently doing the same project.
