Description
The nRF24L01 is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 14mA, a sub μA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01 provides a true ULP solution enabling months to years of battery lifetime when running on coin cells or AA/AAA batteries .GETTING STARTED WITH ARDUINO – NORDIC NRF24L01 RADIOS
In this tutorial, we will use a pair of Nordic NRF24L01 Radios to communicate between two separate Arduinos. NRF24L01 radios are very cheap boards, ideal for short range communication between multiple devices. We will set up one Arduino as a sender where by it will send the analog data that comes from our potentiometer and a second as a receiver that recieve those data and light an LED accodring to the data received – for this you will need two Arduinos and two NRF24L01 Radios.Step1: Hardware required
Step2: Connecting the Hardware
The pins configuration of the NRF24 are shown below![](https://storage.googleapis.com/stateless-www-faranux-com/2018/02/48c4580e-fanjm21j52qanjj.large_-300x173.jpg)

Step3: NRF24 Library setup
Before making the sketch make sure you have the NRF24 library if not, you can download it here After download the library extract it to the arduino library folder as shown below![](https://storage.googleapis.com/stateless-www-faranux-com/2018/02/e90a4ea7-capture-283x300.png)
