A few days ago I received a pair of Easy Radios to help with a project I’m working on. Since I’ve never used these before (having only got my first arduino a couple of weeks ago) I had a dig on the net for information on how to use them. Since this information was quite sparse, I thought I’d put up my experimental rig to show it working. This setup requires 2 arduinos, an easy radio transmitter and an easy radio receiver.  First, the transmitter layout.

Now the receiver layout.

and finally the code.

void setup() {
    Serial.begin(19200);
}
void loop() {
    if (Serial.available()){
        Serial.print(Serial.read(), BYTE);
    }
}

#transmitter code
void setup() {
    Serial.begin(19200);
}
 
void loop() {
    Serial.write("Hello\n");
    delay(1000);
}

This should result in the receiver outputting “Hello” over and over across the USB serial in the arduino environments serial monitor. If you have any problems, feel free to give me a shout! Oh, make sure you unplug the easy radio receiver from the arduino before flashing it, it’ll throw nasty errors otherwise. (Simply unplug digital 0 pin on the arduino board)
