 Bigger Bigger  Smaller Smaller  Reset Reset

I am working on a model train set, and many years ago I started using an 80c451 to do all the controlling and sensing.

I want it to be autonomous, but don't want to program EPROMS, I toyed with using an FRAM and program with a parallel port, then stumbled across this site.

It is looking like the Arduino Mega 2560 is perfect, (built in uP, Flash, lots of I/O) and coupled with the WiFi Shield looks like it is just up my alley.

The description says the WiFi needs another board (presumably a micro-controller board, maybe the Mega 2560?) but doesn't say what is compatible.

Can the WiFi Shield be used with the UNO?

How do the boards interconnect? Does one stack on top of the other (I see some boards have pins on the bottom and sockets on the top for stackability.)

I seem to be missing some basic information to get the ball rolling.

Thanks for your help,
Mark.

Did you find this page: http://arduino.cc/en/Main/ArduinoWiFiShield? I think it may have the "basic information" you're looking forregarding the WiFi shield.

Per that page, the WiFi shield does work with the Uno and the Mega and would require either.

But you'll still have to program your Arduino! There's no way round that, but I assure you it's quite painless. smiley

What do you need WiFi for? Model trains can be easily controlled by an Arduino without it. You'd be better off investigating motor shields. These can control both the speed and the direction of your locos and some have servo outputs to allow you to change points.

I am developing a system to operate my N-Gauge trains with battery power and radio control using Deltino modules http://www.deltino.com/. They are very very small Arduino compatible boards with 2.4Ghz transceivers and motor drive h-bridges included.

I also plan to use a separate Arduino Uno to detect where my trains are using LDRs (Light Dependent Resistors) under the track. The Uno will also control 2 automatic fiddle-yard turntables (at each end of my layout) and points so that even though I don't have space for a continuous loop I will be able to sit back and watch trains running.

I will be controlling all this with my own PC software.

Let me know if I can help.

They look pretty neat.
