NRF24L01 Wireless receiving and transmitting

This experiment bases on the wireless transmission of Arduino board, NRF24L01 is a wireless transmission module that data is sent from sending side and received by Listener side. The data sending is controlled by the button of sending, a frame of data is sent by pressing down the button once in one second. The data can be seen in the Arduino IDE compiler serial monitor real time. The LED will lights up if the listener side receive valid data.

Wiring diagram as following:
Sending (TX)

Receiving (RX)


How the cables go:
Arduino uno ---nRF24L01
3.3V    ---------------    VCC
GND   ---------------    GND
7         ---------------    CSN
8         ---------------      CE
11      ---------------    MOSI 
13      ---------------     SCK
12      ---------------     MISO
Null   ---------------     IRQ
