I'd advise using at least a capacitor of between 1 to 10 uF between the Vcc and Ground terminals of the nRF24L01 module, which will help regulate the input voltage and reduce any fluctuations.

Well, I finally got it done! Tutorials 1-3 for the nRF24L01 have been completed with write-ups for the PIC line of processors (PIC18F452 in these). I forgot to change one thing in the project build options though, and it will likely make some weird directories on your machine if you try to compile the source. Tutorial: Ultra Low Cost 2.4 GHz Wireless Transceiver with the FRDM Board Posted on July 20, 2013 by Erich Styger For my embedded systems lecture I need a wireless connection to the robot we will develop during that course. nRF24l01 module is in fact a radio transceiver module and it operates on 2.4 GHz frequency. This module has the capability to send and receive data simultaneously and this can be used for your various IOT projects . By display it is a very small size module but it's features are astonishing. Just connect pins on the same name on Arduino board and nRF24L01 wireless module: Connecting nRF24L01 and Arduino4. Schematic is very universal and fits for all the Arduino's: UNO, DUE, MEGA, Leonardo, Yun etc. (Arduino 1.0 (R3) standard, but also with older boards) SPI signals are in the ICSP connector. Since these are radio modules, you'll need at least two modules to talk to each other. Duplicate the connections between another RedBoard and nRF24L01+ module. Don't forget to attach the antenna to your nRF24L01+ if you have the RP-SMA version. Hi Leif, Firstly since you are having coms issues I'd comment out the button controls in the main loop of the controller code. You already set some values in the array during setup so I'd replace the main loop with the following for a simple debug. nRF24L01 and UNO R3 Tutorial - Page 4.
