GSM controlled home appliances

i am making project named above.Now I have 3310 mobile and i have reasonable knowledge of Assembly language.i want to interface 3310 to a microcontroller and in output i want 8 logics as an output.in which 6 should be on/off (e.g: lights) and 2 should be variables like varying the speed of fan or limiting Air-condition or any thing else.i dont know hw to code AT commands or how to connect it to microcontroller.
i need ur help guys.its my final year.

NOT USE AT MICROCONTRLLER B/C BAUD RATE:(

I'm pretty sure the Nokia 3310 does not support AT commands.

The Sony Ericsson T610 supports AT commands and is quite cheap these days

or use a GSM modem, will cost you around $20 and works well, fits in project easily.

can you suggest GSM Modem which has $20 price?

go for SIM300 from simcom.

if you are good in AVR you can edit the code for your same application of Device controlling using mobile...go to following german website...dont worry u just need to download code...code is not in german...its assembly and also working....
