Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:
Remote sensors for temperature, pressure, alarms, much more
Robot control and monitoring from 50 feet to 2000 feet distances
Remote control and monitoring of nearby or neighborhood buildings
Autonomous vehicles of all kinds
These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor nRF24L01+ chip.The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller.
In this video we have shown how to interface the Point to Point & point to multipoint communication of nRF module with Arduino UNO.
