=== The code ===
Now we will load the '''receiver''' example code from the RadioHead Library.
Load the sketch '''file -> Examples -> RadioHead (or RadioHead-master) -> feather -> RadioHead69_RawDemo_RX'''
{{ambox-stop|text=We will have to modify the code before uploading it to the Arduino Uno!}}
{{underline|'''Update for Interface:'''}}
No update are required for the interface as we the following the wiring for ATmega328P:
<syntaxhighlight lang="c">#if defined (__AVR_ATmega328P__) // Feather 328P w/wing
#define RFM69_INT 3 //
#define RFM69_CS 4 //
#define RFM69_RST 2 // "A"
#define LED 13
#endif
</syntaxhighlight>
{{underline|'''Update for frequency plan:'''}}
The frequency used by the receiver RFM69HCW must be exactly the same as th emitter! z is free for use, please select your own frequency in that range.
Locate the following lignes:
<syntaxhighlight lang="c">// Change to 434.0 or other frequency, must match RX's freq!
#define RF69_FREQ 915.0
</syntaxhighlight>
And update it to:
<syntaxhighlight lang="c">// Change to 434.0 or other frequency, must match RX's freq!
#define RF69_FREQ 433.0
</syntaxhighlight>
{{underline|'''Activate the Serial Line:'''}}
No need to change here as we are using an Arduino UNO.
Voilà, We are ready to compile and upload.
