Intro: Arduino UNO Wireless Communication With PC
Use Arduino BATT & RF UART Shield , can be easy to implement wireless communication between PC and UNO. the shield use 2 AAA battery and provide 5V to UNO , so the UNO can be wireless working and communication to PC via 2.4G RF signal.
The RF module used LC-1000 which is 0dBm output power , the open distance can be reach to 30m and max baud rate support to 57.6Kbps.
Here have some reference code for using this shield,
