Welcome to our beginner’s guide to IoT development with graphical programming tools. In recent years, the phrase “Internet of Things” (IoT) has gained immense popularity as more objects become connected to the internet. IoT refers to scenarios where everyday objects, which are not typically thought of as computers, are equipped with computing capability and network connectivity.
With IoT technology, these devices can generate, exchange, and consume data with minimal human involvement. As a result, businesses have introduced IoT-related products and services, leading to significant growth in the IoT market. The history of IoT can be traced back to the integration of intelligence and sensors into physical objects, driven by the development of the internet itself.
The Internet of Things has immense potential to bring economic value and advancements. However, it also raises concerns regarding privacy and security. In this guide, we will explore IoT development and how graphical programming tools can help simplify the process of creating IoT applications.
How does the Internet of Things (IoT) work?
Internet of Things (IoT) technology enables web-enabled smart devices to connect and communicate with each other. These devices, such as smartphones and tablets, use embedded systems like sensors and processors to gather data from their surroundings. The collected data is then transmitted to an IoT gateway, which acts as a centralized hub connecting IoT devices and sensors to the cloud.
IoT devices can be connected to the cloud through various communication methods, including WiFi, Bluetooth, and satellite networks. Modern IoT gateways facilitate bidirectional data transmission between the cloud and IoT devices. This allows for the uploading of sensor data to the cloud for processing and the sending of commands from the cloud to IoT devices.
Once the data is transferred to the cloud, it can be processed and used to trigger actions. For example, it can send alerts to users or automatically adjust device settings. IoT-enabling technologies, like RFID and NFC, make it possible to interactively identify and connect physical objects to the internet, expanding the scope of IoT applications.

Introduction to LoRa and LoRaWAN for IoT Development
LoRa is a leading technology for long-distance and efficient wireless communication in IoT applications. It utilizes the Chirp Spread Spectrum (CSS) modulation technique to transmit data over long distances with low power consumption and high sensitivity. LoRaWAN, on the other hand, is a network communication protocol for IoT devices based on LoRa technology. It enables the connection of IoT devices to a centralized network and facilitates bidirectional data transmission.
One of the key advantages of LoRaWAN is its ability to provide security and control over data communication through encryption protocols and a decentralized architecture. To implement LoRa connectivity with the LoRaWAN protocol, an application server and gateway infrastructure are required. The Things Network (TTN) and The Things Stack (TTS) are two popular options for deploying a LoRaWAN network.
When it comes to developing IoT devices based on LoRa technology, there are visual support tools available that simplify the process. Platforms like Arduino and Raspberry Pi provide an intuitive visual programming interface, allowing developers to easily configure the logic of IoT nodes. These tools automatically generate the corresponding code in specific programming languages, such as C++ or Arduino, which can then be compiled and uploaded to the hardware prototype.
Advantages of LoRa and LoRaWAN for IoT Development:
- Long-distance wireless communication
- Low power consumption
- High sensitivity
- Security and control over data communication
- Decentralized architecture
- Support for visual programming tools like Arduino and Raspberry Pi
