“There are many wireless communication options when connecting Arduino boards. One of the most popular ones is the Wi-Fi. It works well at small distances, and around Wi-Fi hotspots, however when the modules need to connect over long distance at areas where Internet is not present, Wi-Fi is not an option. Luckily there is a great and easily available alternative - the LoRa (Long Range Wide-area network) modules allow sending small packets of data between modules over very long distances (5 Km or more) . Visuino has support for a number of LoRa Modules, and I was planning tutorial for quite some time, since I had some Adafruit LoRa modules. However, recently the great people at Makerfabs, sent me 2 RFM95W 868MHz based LoRa Shields, and even a great Arduino UNO compatible Maduino UNO board. The Makerfabs modules are of exceptionally good quality, and I decided to make this tutorial with them. In this tutorial I will show you how easy it is to install the LoRa shields on 2 Arduino UNO boards, and program them with Visuino to transmit data over long distance.”
