Transceivers

You will need to install this library to make the transceivers work. You can download the zip file and under Sketch >> Include Library, select "Add ZIP Library..." or extract the zip file and save the contents in "C:\Users\username\Documents\Arduino\libraries". For a more complete set of instructions for installation, please read this file (Thanks to Andrew for creating this doc).

• • MISO connects to pin 12 of the NANOMOSI connects to pin 11 of the NANO

  • SCK connects to pin 13 of the NANO

  • CE connects to pin 9 of the NANO

  • CSN connects to pin 8 of the NANO

  • GND and V+ of the NRF24L01 are connected to GND and 3V3 (Not 5V or Vcc) of the NANO

  • IRQ connects to nothing
