3. Connect the Makerduino to Computer by the USB cable.

 

4. Download the Makerduino demo code EB - 2KM Long Range RF Link Kit.zip. Unzip the code directly into the libraries folder.

 

5. Open Makerduino IDE, choose the right Board and Serial Port. Open the sketch EB_2KMLongRangeRFLinkKit.ino and upload it to the Makerduino.

 

The following is the demo code for EB - 2KM Long Range RF Link Kit. (Note: It could be a little different from the code file downloaded. Please follow the downloaded file.)

// constants won't change. They're used here to

// set pin numbers:

const int Pin0 = 4;    

const int Pin1 = 5;

const int Pin2 = 6;

const int Pin3 = 7;

const int Pin4 = 8;

//set low state ;

int State0 = LOW;

int State1 = LOW;

int State2 = LOW;

int State3 = LOW;

int State4 = LOW;

 

void setup() {

  // initialize the Recever pins as  input:

pinMode(Pin0, INPUT);

pinMode(Pin1, INPUT);

pinMode(Pin2, INPUT);

pinMode(Pin3, INPUT);

pinMode(Pin4, INPUT);

  Serial.begin(9600);

}

void loop(){

  // read the state of the pushbutton value:

 State0 = digitalRead(Pin0);

 State1 = digitalRead(Pin1);

 State2 = digitalRead(Pin2);

 State3 = digitalRead(Pin3);

 State4 = digitalRead(Pin4);

if(State4)//State4 act as the flag of received message.

//it equals 1 when received message, else equals 0.

 {

    //print matched flag of the received message;

    if(State0){Serial.println("received data:A");}

    if(State1){Serial.println("received data:B");}

    if(State2){Serial.println("received data:C");}

    if(State3){Serial.println("received data:D");}

 } 

else         

 { 

   //no message received.

 }

  delay(200);

}

 

 

6. Check the Results. After the sketch is successfully uploaded, let's open the Serial Monitor. Push the button from button0 to button3. The Monitor will display following information.
