Taking your nodebot wifi

Controlling your nodebot using a USB cable is great and all, and obviously you could shell out and grab a sparkcore or some other dedicated controller but what if you've got a standard arduino and you want to take an existing nodebot wireless?

Bluetooth is an option and there's this excellent JohnnyFive wiki entry that will help you there. Bluetooth can be a bit flaky though and it's range is pretty lousy. You can also look at things like XBees and what not using point to point serial, but these are expensive and very fiddly to get working.

Really, what we want is a method of transferring data over a nice, simple, standard method, requiring little configuration, low cost and we can utilise a whole stack of the code we've already produced.

Enter the WiFi232 module. These little beauties are [available from AliExpress for $12 each](http://www.aliexpress.com/item/USR-WIFI232-T-wifi-to-uart-tt
