I am new to Arduino programming and to this forum. I am interested in developing a home security/automation sytem that will notify me of security breaches and allow remote access control thru my cell phone. Could someone give me the recomended hardware part numbers to accomplish this. For example, should I start out with an Arduino Uno or just buy the Mega? Do I need to purchase a WiFi or ethernet GSM shield?
Thanks in advance for any help you might give.
