Topic: arduino networking on a budget, can it be done? (Read 1 time) previous topic - next topic

My project requires "some kind of remote communication to the PC" in order to work.  It doesn't have to be wireless, wired is fine.  The project is a desktop JAVA app that can either use the serial data, or use web data gotten via PUT and GET (see https://github.com/jjg/RESTduino)

I've just priced all the available options: Ethernet shields, WiFi sheilds, XBee (which I could make work I think)...and it's all really just too expensive.

I need to keep the price of the finished project super super cheap.

Is there another way to get this done?  I guess the short question is "what is the cheapest way to maintain comms between PC and the ardunio?"

I guess I could just use a super long USB cable and use the serial data?  That seems ghetto though...there's got to be a cheap way to do ethernet?

Just use the USB cable. It fits well with the ghetto thinking and budget.

Ethernet shield: $25. ArduServer.com

Maybe later... product not yet released: DCDWireless.com, if from-sensor-to-Arduino enough.

Or why not just a serial connection between them?

This is from a recent posting. I've just ordered and going to try out bluetooth.

Can't you can get an old - win95/98 - PC/ laptop from a digital scrapheap for free. Connect the Arduino to its serial port and use the PC's network card ...

It takes some tinkering (python/php/...) but it could be the cheapest solution -  not energy efficient although ;)

Maybe serproxy is an option - http://www.lspace.nildram.co.uk/freeware.html
