I am looking for any documentation that would allow me to use 2 or more modules either to talk with one another or to connect to my Arduino UNO. I would also like to retrieve date over the Internet via it connecting to my home network. Please advise.
For two arduinos to talk to one another, use either WIFI or Bluetooth (master AND slave modules, slave cannot talk to other slave, and same with master).
To get data from your home network, again use Wifi or an Ethernet shield.
