4. What is Arduino®

Arduino® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino® boards are able to read inputs - light-on sensor, a finger on a button or a Twitter message - and turn it into an output - activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing).

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. It’s perfect for building inexpensive short-range wireless networks for home and building automation, sensor networks, automated meter readings, wireless alarm and security systems, industrial monitoring and control, and many more applications!

The RFM69HCW transceiver module operates over a wide frequency range, including the 315, 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. All major RF communication parameters are programmable and most can be set dynamically. The RFM69HCW is optimized for low power consumption while offering high RF output power and channelized operation.

The VMA348 RFM69HCW transceiver breakout board brings out all the pins and the antenna connection. Each module comes with headers pre-soldered, a 3.3 V voltage regulator and level shifter that can handle 3-5 VDC power and logic so you can use it with 3 V or 5 V devices. You will need to solder a small piece of wire to create your antenna or you can add a UFL or SMA edge-mount connector and attach an external antenna.

By using the provided library, the frequency of the board can be set with 61 Hz precision to any frequency from 240.0 MHz to 960.0 MHz.

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®.

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. reading and sending the status of a PIR sensor to the Arduino® so you can make a relay switch or control LEDs…

Not covered by warranty:
– all direct or indirect damage caused after delivery to the article (e.g. by oxidation, shocks, falls, dust, dirt, humidity…), and by the article, as well as its contents (e.g. data loss), compensation for loss of profits;
– consumable goods, parts or accessories that are subject to an aging process during normal use, such as batteries (rechargeable, non-rechargeable, built-in or replaceable), lamps, rubber parts, drive belts… (unlimited list);
– flaws resulting from fire, water damage, lightning, accident, natural disaster, etc….;
– flaws caused deliberately, negligently or resulting from improper handling, negligent maintenance, abusive use or use contrary to the manufacturer’s instructions;
– damage caused by a commercial, professional or collective use of the article (the warranty validity will be reduced to six (6) months when the article is used professionally);
