nRF24l01+ 2.4GHz Wireless Arduino Transceiver Code

The nRF24l01+ transceiver is a fantastic and cheap way to get your Arduinos talking to each other wirelessly. It’s also very easy to use thanks to some great libraries:

Each library has some great examples and is fairly well documented, especially the RF24 libraries.

Feel free to download the libraries and use the included examples – they are fairly well documented. Also be sure to check out Maniacbug’s website which has some great posts on the nRF24l01+ modules.

Also, here’s a pinout that will prove to be very helpful:

  1. I just wanted to verify the pin numbering before wiring up a header socket…

    I believe that the pin with the yellow box is #1, then 2 is across from it to the left as pictured, and 3 is above it. The whole layout is then:
    8 7
    6 5
    4 3
    2 1
    as shown in your image.

    • That is correct. There are small numbers on the pins in the picture above but they are a little hard to see.

    • Thanks! To my 50+ year-old eyes, they looked like part of the solder contour. With a few ctrl++’s, I see what you’re talking about.
