Any arduino coders here?

I think you are slightly misunderstanding what an arduino is. You get a full prototyping board and 'environment', once you have finished prototyping you use an atmel IC in your production device which even if you are going to buy from farnell start at 38 english pence ex vat...

Fair enough....I should perhaps wind my neck in then (my full prototyping enviroment is a breadboard & box of caps/resistors!). Does the arduino proto enviroment allow you to swap around the MCU pins? ....so for example if the HPWM pin is on pin 3, with a PIC you can often switch a module (HPWM, UART etc) to another pin via an internal register setting - of course you then have to swap around all the connections to marry up with the new pin config - are the arduino pins hardwired per function? Such pin swap flexibility is quite important for best pcb layout. Obviously, once you've done your coding, the next step is to get it onto a pcb layout....and it's best to proto with the same pin config you're gonna have on your pcb layout (and being able to swap the pins about aka PIC is very useful towards helping the best pcb layout)
