In this tutorial to learn sending and receiving random data from NRF24L01 Wireless Transceiver using Arduino nano. we will learn how to make Radio Frequency wireless communication using the nRF24L01+PA transceiver module is designed to operate in 2.4 GHz worldwide ISM frequency band and uses GFSK modulation for data transmission. The data transfer rate can be one of 250kbps, 1Mbps and 2Mbps. The NRF24L01 module is a low-cost ultra-low power, bi-directional transceiver module. The module can achieve data rates as high as 2Mbits! and uses a high-speed SPI interface in order to communicate with the Arduino and IOT.
