Hi,
I have a design plan:

  1. nrf24l01 transmitter send message let nrf24l01 receiver turn on a LED for 1 second and send feedback to transmitter ;
  2. after 2 second nrf24l01 transmitter send message let nrf24l01 receiver turn on LED for 2 second and send feedback to transmitter ;
    …
    till 5 seconds.
    Are there any examples or coding clue please?
    Thanks
    Adam

You’re welcome. Here is also a basic example that you may try. This one shows how to interface NRF24L01 with Arduino. You’ll also get idea about configuring the module as transmitter and receiver. Sample codes are given.
