Communication
nRF24L01+ library requiring very little code along with YouTube videos showing all available features.
Send dynamically-sized data packets, with or without dynamically-sized acknowledgement packets, with less complication than other libraries. The library also supports controlling the radio with only 2 pins on ATtiny and ATmega microcontrollers!
Maintainer: Dave Parson
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
