I've looked at the mbed before; while I like it for what it is, what I don't like is the "web based programming environment"; it would be a fine thing if you could host it yourself, but I don't see that as something that exists. What happens if the company behind mbed goes out of business, but you have clients or others to support? What do you do if you've built up a large codebase for some device, and there is no longer a way to compile it? These are main reasons that have turned me off of mbed...

ARM actually makes the mbed, and provides the development software. They aren't likely to go out of business!

If you want something similar with conventional development tools, look at the LPCXpresso boards:

They have the advantage of debugging facilities.

If you can't find the spec. for that motor, ditch it and find one that does have a specification. We will then be able to help you.

It's impossible to say, there are no data. It's always a good idea to buy parts with data sheets. It will require some form of driver, like a MOSFET; you won't be able to connect it directly to an Arduino output.

I've ordered from them a couple of times, but I didn't notice that. A lot of companies do it, such as RS and Farnell, but they mostly supply trade customers. Companies mainly supplying hobbyists tend to quote prices including VAT. I don't think there is any legislation about it for on-line buying, unlike retail sales and adverts.

Pin 2 is the Tx data pin.

Just pick one of them and try it! Try that test of mine first, it might save you some time.

They appear to use AM, so I'd start by simply turning the input to the Tx on, and checking the output of the Rx to see if the signal is received. If that works, try sending some data. A scope would be useful.

Data sheet for those modules?

Try a builders merchant, it's often used for cleaning brickwork. That's where I get mine.

I use photo-etch with resist-coated boards. Transparencies are printed with a cheap HP inkjet printer, and I use a simple home-made UV exposure unit. I get excellent results - 8/8 mil tracks if I need them (I've done 5/5 mil as an experiment), but I usually use 10/10 or 12/12.

I'm in the UK, and most insurance policies specifically exclude cover if a car is modified. Your's might not have such an exclusion, of course.

It will also invalidate the insurance policy, which will make the OP liable for any damage or injury he causes if the car is involved in an accident, even if it wasn't caused by the modifications.

The maze will be illuminated, presumably, so ordinary light sensors should work.
