7 Most Used Programming Languages For IoT Projects

IoT is one of the most popular technologies today. With the urban renewal and retrofitting program of Smart City Mission, the Indian government is trying its best to contribute to the mission of Smart Cities. To start a career as an IoT developer there are some programming languages that are an absolute must and  govern this space.

In this era of IoT governing many different industries and applications, here are the top programming languages that rule the IoT projects.

1. Java

Java has an incredible policy of “write once, run anywhere” (WORA), which is the program’s ability to run on all common Operating Systems. This forms a good choice for IoT projects as the code is easily deployable in different devices and chips using Java Virtual Machine (JVM). Using JVM the code can be transferred to  smartphones and servers. Java also provides the hardware secure libraries, capable of accessing the genetic code.

2. C

C has been the backbone of many platforms till today. IoT is one such spectrum where it has a lot of usage. It can work directly with the RAM and hence it doesn’t require a lot of processing power. This programming language is compiled making it great for IoT projects.

3. JavaScript

JavaScript, most popular for all web browsers and HTML, also finds its use in the space of IoT.

JavaScript is used as the programming language in all the web browsers and HTML. JavaScript makes things easier as it makes the devices interoperable. Most of the work is focused on the servers and hubs that collect information and then store it. It has an end-user scripting and is easy to learn. The advantage with JavaScript is that in the process of developing an IoT system,  embedded programmers need not learn different syntax if they are using JavaScript because its syntax is very similar to C. JavaScript developers in IoT have sophisticated frameworks and engines like CycloneJS, IoT.js, JerryScript, Duktape, etc. specifically designed for constrained devices.

4. Python

Python began its journey as a high-level scripting language. It has a large number of useful libraries and can get more stuff done with fewer lines of code. It is popular for web applications but also has its usage in IoT. Many of the data analysis involved with IoT systems is done using Python. With a compact yet readable source code, Python is the best choice for managing complex data streams without having to maintain equally complex codebases. But the language is not very popular in areas where the computational requirement is high. It is generally preferred for simple, modular projects.

5. C++

C++ has seen an increase in its usage for IoT solutions because of the processors being more and more powerful. It is an alternative to C if the devices require more complex tasks. The language also causes to utilize different languages including C#, Java and Python.

6. Swift

Swift is popularly known for building applications for Apple’s iOS and Mac OS devices. Apple is looking forward to inculcate smart solutions and that makes it a part of the IoT. To make the devices interact with an iPhone or an iPad, it is easy to build an application using Swift. To make the iOS devices center of the home network of sensors Apple is shifting from C to Swift and is therefore building libraries that can handle most of the work.

7. PHP

According to an Eclipse Foundation survey, 11.2 percent of developers said that they are including PHP in their code stack and it was a language that was mentioned most often by them. Not as popular as the other big players, PHP comes around as the best support for IoT with it being affordable and most flexible language platform. Both together can create new and exciting ways for users to interface the digital world

The Best Language For IoT

The language to be used depends a lot of the needs of the IoT project. But according to the present scenario, Java has the majority of usage compared to the other languages. Each language is different in its own way and provides different advantages for different projects. The language chosen should suit the needs of the end-use applications. Currently, an amalgamation of these languages seem to do the job best.
