Use with Arduino

The following steps show how to use EB - 433/315MHz RF Transmitter with Makerduino.

Materials

  •  Makerduino
  •  Electronic Brick Shield
  •  EB - 433/315MHz RF Transmitter
  •  A/B type USB cable 
  •  Female DuPont wires

Steps

1. Connect Electronic Brick Shield onto Makerduino to bring out all the Makerduino Pins.

aeProduct.getSubject()

 

2. Connect EB - 433/315MHz RF Transmitter to Makerduino as following:

 

         aeProduct.getSubject() 

     the actual connection may like this

                           aeProduct.getSubject()

 

 

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

 

4. Download the Makerduino demo code EB - 433/315MHz RF.zip. Unzip the code directly into the libraries folder.

 

5. Open Makerduino IDE, choose the right Board and Serial Port. Open the sketch EB_433/315MHz_RF_Transmitter.ino and upload it to the Makerduino.

 

The following is the demo code for EB - 433/315MHz RF Transmitter. (Note: It could be a little different between downloaded file and following demo code. Please follow the latest downloaded file.)

 

/*

 EB - 433/315MHzHz RF Transmitter demo code

 

  Transmit message "Hello" to the Receiver every other second

 

*/

#include <Wire.h>

#include <VirtualWire.h>

 

int RF_TX_PIN = 2;

 

void setup()

{

  vw_set_tx_pin(RF_TX_PIN); // Setup transmit pin

  vw_setup(2000); // Transmission speed in bits per second.

}

void loop()

{

  const char *msg = "Hello";

  vw_send((uint8_t *)msg, strlen(msg));  // Send 'Hello' every 1000ms.

  delay(1000);

}

 

6. After the sketch is successfully uploaded. The EB - 433/315MHz RF Transmitter transmits “Hello” per second.

 

 

The following steps show how to use EB - 433/315MHz RF Receiver with Makerduino.

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

4. Open Makerduino IDE, choose right Board and Serial Port. Open the sketch EB_433/315MHz_RF_Receiver.ino and upload it to the Makerduino.

*/

 

#include <Wire.h>

#include <VirtualWire.h>

 

int RF_RX_PIN = 2;

 

void setup()

{

  Serial.begin(9600);

  Serial.println("setup");

  vw_set_rx_pin(RF_RX_PIN);  // Setup receive pin.

  vw_setup(2000); // Transmission speed in bits per second.

  vw_rx_start(); // Start the PLL receiver.

}

 

void loop()

{

  uint8_t buf[VW_MAX_MESSAGE_LEN];

  uint8_t buflen = VW_MAX_MESSAGE_LEN;

  if(vw_get_message(buf, &buflen)) // non-blocking I/O

  {

    int i;

    // Message with a good checksum received, dump HEX

    Serial.print("Got: ");

    for(i = 0; i < buflen; ++i)

    {

      Serial.print(char(buf[i]));

      //Serial.print(" ");

    }

    Serial.println("");

  }

}

 

5.  Check the Results. After the sketch is successfully uploaded, let's open the Serial Monitor. You can receive the following information.
