Popular Graphical Programming Languages for IoT Development

In the world of IoT development, there are several popular graphical programming languages that play a vital role in simplifying complex coding tasks. These languages help bridge the gap between developers and the intricacies of IoT systems, making it easier to build and maintain efficient projects. In this section, we will explore 11 widely used programming languages in IoT, each with its unique features and advantages.


C is a reliable and reasonable choice for embedded system development. With its proximity to machine language and processor independence, it allows developers to optimize code for specific hardware. Its efficiency and low-level control make it a popular choice for IoT devices with limited resources.


C++ is a middle-level programming language designed for system and embedded programming. It offers features like data hiding and stronger typing, making it suitable for resource-constrained devices. With its support for classes, C++ enables developers to write code that is easier to maintain and understand.


Go, an open-source language developed by Google, combines performance and security with the speed of a dynamic language. It excels in handling concurrent input, output, and processing on multiple channels simultaneously. Go’s simplicity and ease of use make it a popular choice for IoT development.


JavaScript is widely used in web servers, mobile apps, and IoT systems. Its event-driven nature, along with a garbage collector for memory management, makes it well-suited for managing IoT devices and processing real-time data. JavaScript’s versatility and large developer community make it an excellent choice for IoT projects.


Python is an interpreted programming language known for its readability and clean syntax. It supports database integration, offers a wide range of libraries and modules, and is particularly handy for edge devices, gateways, and cloud-based IoT systems. Python’s simplicity and extensive ecosystem make it a popular choice among developers.


Rust is an open-source compiled language that provides memory safety, concurrency, and performance. It eliminates race conditions and is commonly used for embedding in other languages, writing low-level code, and programming with specific space and time requirements. Rust’s focus on safety and performance makes it a suitable choice for IoT development.


Java is an object-oriented language known for its portability and strong security features. It offers high levels of networked encryption and authentication, making it ideal for secure IoT systems. Java’s extensive APIs and robust community support contribute to its popularity in the IoT development space.

Assembly language:

Assembly language is a low-level programming language specific to a particular computer architecture. It is known for its compact and optimal code generation. Although it requires deep technical knowledge, it offers precise control over hardware and is commonly used for developing IoT systems that demand fine-grained optimization.


ParaSail is a compiled, object-oriented language designed for parallel processing in IoT systems. It supports both implicit and explicit parallelism and provides parallel evaluation semantics. ParaSail’s focus on parallelism makes it a powerful tool for developing high-performance IoT applications.


R is a programming language widely used for statistical computing and graphics. It is particularly popular among statisticians and data miners for data analysis. With its extensive range of statistical and graphical techniques, R serves as a valuable tool for analyzing and interpreting data collected from IoT devices.


B# is an efficient embedded control language that can run on low-memory hardware platforms. It supports modern object-oriented features and is designed for portable interrupt handlers and device addressing registers. B# is well-suited for developing IoT systems that require precise control over hardware resources.


Forth is an imperative stack-based language optimized for embedded systems programming. It features interactive execution, compilation of commands, and support for structured and concatenative programming. Forth’s simplicity and efficiency make it a preferred choice for small-scale IoT projects with limited resources.

Addressing the Challenges of IoT and OT Security

The convergence of IoT technology and OT assets introduces significant challenges and potential risks to organizations. While IT networks have matured in terms of security protocols and practices, OT networks often lack robust security measures. To ensure the safety and integrity of IoT and OT assets, organizations must prioritize implementing comprehensive security strategies.

An operational technology assessment is a crucial step in identifying vulnerabilities and establishing a strong security foundation. By conducting an OT assessment, organizations can determine the number of assets connected to their environment, establish baseline expectations, identify critical events for monitoring, and create a roadmap for addressing security gaps. CDW offers a five-layered approach to OT assessment, focusing on detection, definition, decision, deployment, and defense.

By leveraging this approach, organizations can proactively mitigate the risks associated with IoT and OT security. Implementing necessary security measures, based on the findings of the assessment, safeguards against potential threats and unlocks the true potential of IoT technology. It is imperative for organizations to recognize the importance of securing their IoT and OT assets to ensure the continuity and reliability of their operations.
