Hey there! I am working on a project which sends GPS locations through SMS on demand. As it turns out, I'll be needing GSM shield/module, GPS shield/module and, of course, an Arduino Uno board. My question is, can I use these two hardware(s) with Uno simultaneously using h/w and s/w serial? If yes, please suggest some ways and necessary functions. I am aware that the Mega would make the job a lot easier but i cannot because of the cost constraints.
Thanks in advance!
