14Core_NRF24l01We will going to demonstrate here how to use Nordic nRF24L01 2.4 Wireless Radio using Arduino with Joystick Controller. This 2.4Ghz Radio module are base on Nordic Semiconductor nRF24L01+ Chip,

The Nordic nRF24L01+ integrates a complete 2.4GHz Radio Frequency Transceiver, Radio Frequency Synthesizer, and Baseband Logic including the Enhance ShockBurst hardware protocol accelerating a high speed SPI interface for the application controller and low -power short-range transceiver and it has a built in on-board antenna other model it has SMA integrated antenna with a range up to 1100 Meter.

 

Features:

  • 2 ore more Arduino’s be able to communicate wirelessly over a distance.
  • Controlling a nearby buildings
  • Controlling Autonomous vehicles of all kinds
  • Excellent for a remote sensors for temperature, pressure, distance, switching, alarm and more.
  • Controlling and monitoring a robot a range up to 2000 feet distance

We will going to transmits a communication between to Arduinos over NRF24L01 using Joystick

Note: Problem accure when operation because of electrical noise on 3.3v supply, specially when using Arduino Mega and Nano we need to add bypass capacitor across ground and vcc on the module. please see the schematics below.

Note: you need to check the voltage 3.3v power supply, it will distract the operation due to power regulation issues, the average current may be less 15ma.

    Please help me how can i fixed this problem?
