Wireless RF Communication between Arduino and Raspberry Pi using nRF24L01 Module
Here we will use nRF24L01 – 2.4GHz RF Transceiver module with Arduino UNO and Raspberry Pi to establish a wireless communication between them. The Raspberry pi will act as a transmitter and Arduino Uno will listen to Raspberry Pi and print the message sent by Raspberry Pi using nRF24L01 on a 16×2 LCD.
