VMA348 5. Overview General The RFM69HCW module is an inexpensive and versatile radio module. You can use it to send text or binary data between two or hundreds of modules.
VMA348 6. Operation Overview We will connect two radio modules to one another, read the temperature and send the temperature value to another module. Requirements: • 2x Arduino® UNO • 2x VMA348 RFM69HCW module • 1x VMA320 analogue temperature sensor module • 20x jumper wire • 2x USB-A to USB-B cable Connecting Arduino® 1. Connect the VMA348 module to the Arduino® as depicted below. We will only connect one temperature sensor to one Arduino®. V.
VMA348 Programming 1. Download the RadioHead library here and add it to the Arduino® IDE. 2. Go to GitHub and download both codes here. 3. Open the RF69_CLIENT_SEND_DATA code and upload to the Arduino® with the temperature sensor. You should see following output: 4. Open a new IDE with the RF69_SERVER_RECEIVE_DATA code and upload to the Arduino® without the temperature sensor. You should see following output: Now, it’s time to try and send data using all kinds of sensors, e.g.
