Story

In many projects we may need wireless communication between different microcontrollers. For that we are using different modules like XBee/Zigbee, simple RF, Bluetooth/BLE etc. Now on this blog I am going to explain a different wireless transceiver module NRF24L01 which is working on 2.5GHz ISM band frequency.

I was so lazy to work on this module since this is not a breadboard friendly module and I was not having female to male headers. And I was too lazy to make a connection circuit to this module to breadboard. Meanwhile I got an invitation from Collaborizm, a platform for entrepreneurs/engineers/creatives. I was about to have a look on a project on NRF24L01. So I tested my module for the first time.

NRF24L01 is designed for ultra low power wireless applications. It is a transceiver with an embedded base band protocol engine named Enhanced ShockBurst™. The module can be interfaced with Arduino or any other microcontrollers via SPI bus.

Applications

  • In wireless PC peripherals like keyboard, Mouse etc.
  • Remotes
  • Toys
  • Home automation
  • Asset tracking systems
  • Active RFID systems
  • Ultra low power sensor networks

Demo project 

Here I am going to showcase a simple NRF24L01 based transmitter and receiver. Transmitter is act as remote control and receiver will ON/OFF a  LED in accordance with the data received. I am using Arduino pro minis as my microcontrollers you can use your own Arduinos. You can  find the  Arduino library for NRF24l01 here.

Connection 

  • nrf24L01------Arduino
  • vcc-----3.3V 
  • GND----GND
  • MISO---pin12
  • MOSI---pin11
  • SCN---pin10
  • SCK---PIN13
  • CE----pin9

The connection is same for both transmitter and receiver you can find the Fritzing project  files here
