Hello, I am a Control and Automation Engineer from Turkey. My main field of work is prototyping new designs. Most of my products are based on Atmega processors. GSM technology comes in handy when you need a remote control, the troublesome part of GSM is (including the SIM800 module), they have different supply voltages than Atmega processors. Therefore, if you are expecting a small board result from this project, I may disappoint you. I need more details about your project to say something more accurate. good luck in your work
