Best Programming languages for Making Internet of Things Projects

Internet of things is one of the most popular fields of technology nowadays.  The Innovations in this field are too fast to keep up, as more and more devices are getting connected to the Internet every single hour. We know that these devices communicate and transfer data to and from other computers across the Internet, but how do they operate internally? How and in which language are these devices programmed to function just in the way they are supposed to be?


IoT devices do not use any unknown languages we never heard of. Mostly they use the popular languages to work, as they generally use micro-computers like Raspberry PI. The use of general-purpose programming languages encourages more developers to get their hands-on IoT research. In a survey conducted by the Eclipse Foundation, Java, C, JavaScript, and Python are found to be the top 4 programming languages used for IoT based applications.

Which one to take?

You really can’t go wrong taking any of the above-mentioned programming languages. Choosing a programming language for IoT is very similar to choosing a programming language for any desktop OS, as Raspberry PI uses a Linux version. Eclipse Foundation survey also states that more than 5% of developers are using 14 other programming languages to go with their IoT projects.

Below we mentioned some of the best languages you can go with.


Java is ever so popular in the programming community for it’s “write once and run everywhere” feature. It is the same feature that makes Java a great language for IoT projects. Surveys from Eclipse and states that Java is the most favorite language of IoT developers.


Once a Java program is written, it can be run on any system that supports Java Virtual Machine like smartphones, desktops and even on very small devices. Introduction of the Java ME or the micro edition boosted the developer count. As of today, the main focus of Java IoT developers is the Java SE Embedded, which is very close to the standard edition.


Even though it is popular for being one of the old languages, developer community still loves to use C in their IoT devices. The cluttered syntax provides a million ways to make errors and get stuck in your way, but that doesn’t demotivate the developers as the community seems to grow bigger, slowly. Being a low-level programming language helps a lot and C allows you to squeeze every ounce of its performance to make super-efficient products.


Python in IoT is a no-brainer, lately the language is popping in every engineering field we can think of. The performance is not an issue anymore as the computational power of the embedded devices is increasing day-by-day. The availability of many library functions and the ability to perform operations with just a few lines of code makes Python a very powerful language for IoT.


When someone says JavaScript, the first thing that comes to our mind is the frontend development and frameworks. All of that has changed since the explosive growth of Node.js, which become the go-to language for backend development. Since the IoT programming involves a lot of backend programming, communicating protocols and stuff, JavaScript is vastly used. About 41.5% of the developers in the Eclipse survey stated that they use JavaScript.


PHP is once a very popular language for backend development and is still popular with the blogging community. The language has a great scope in IoT and can be used extensively for the projects.
