Using Low-Cost Wireless Modules

It’s easy to send text information in one direction using a wireless link between two Arduino-controlled systems that have inexpensive radio frequency (RF) data modules, such as the transmitter and receiver modules shown in Figure 16-1. These modules are usually sold in pairs and are known as RF Link modules or kits. ...
