did I do well?

I did this:

www.BTInterface.com

I mean, you can get your arduino to speak! to play sounds! you can control it wirelessly over bluetooth.

did I do well?

I can get my arduino to speak, with aid from the tone library and also with a MP3 module. I can do it via Bluetooth, wifi, RF, and IR.

good for you

The idea about BTInterface was modeled around the Arduino.

A wireless interface to provide buttons etc. to use it. (coz it don't have none).

It kind of took off, I provided speech and sound effects and stuff and the ability to customize the screen etc.

One simple little Bluetooth module is all that is required :)

Seriously when it gets this good then one starts to wonder what is actually possible, hence this vid:

extremely difficult commands from the Arduino are sent such as:

Send ("say no stupid, that was a black one");

or another extremely difficult command to send might be:

Send ("sms 07951555555 this is a text message");

Is this the same thing you mentioned here: http://forum.arduino.cc/index.php?topic=160775.0 and here: http://forum.arduino.cc/index.php?topic=145241.0
