How to use ELRS Receiver with Arduino?

I have a ELRS 2.4GHz NANO ExpressLRS Receiver BETAFPV NANO 2400 RX and a Arduino Uno. I have no idea how to connect the two together and how to get the output. My questions are:

  • How to bind the receiver to the transmitter (Radiomater Pocket)
  • How do connect the Arduino to the receiver (what pins should I connect the RX and TX to)
  • What code do I have to upload to the Arduino for me to be able to use the receiver outputs in a drone to control different features

Thank you in advance
