6 Fascinating IoT Projects Using Arduino in 2023


If you love electronics, there is a huge probability that you have heard about the Arduino board. Even if you are pursuing electronics as a hobby, there has to be a time when Arduino boards were on your holiday shopping list. For those of you who are unaware of the wondrous marvel of electronics. Arduino is a board that is small in size. To be very precise, it resembles a credit card that you keep in your pocket. 

The wondrous part about Arduino, along with its size, is the computing capacity that it packs. You can find that you can run even a full Linux distro off it. Needless to say that when you combine both the size and the punch that it packs, Arduino becomes the central component in many IoT or Internet Of Things applications.

With that being said and without any further ado, let us begin the list of the best IoT projects using Arduino:

IoT Projects Using Arduino

1. A Panel That Would Track Sunlight

Solar energy is one of the renewable sources of energy. It produces clean energy. Which in the current day and age is very important. Considering the rapid decline in the number of carbon-based fossil fuels and the sudden surge in carbon footprint and Global warming, our dependence on such a clean energy source would only further.

So, if you happen to already be a solar energy aficionado by going on a large scale farm or planning to start small, or you just like solar energy in general. You would need a solar panel regardless of the kind of person you are. Since solar panels are fixated, meaning they do not inherently move as the day progresses, if you have a solar panel installed, you are losing a lot of sunlight, which in turn means losing a lot of energy.

What you can do is make a small sun-tracking panel. You would be able to track the solar energy level in your area, and you would also be able to ascertain which position would yield the most amount of energy.

You would not be requiring a large amount of equipment or would not be doing any heavy spending. However, with such a small amount of money, you would be able to make a huge impact on the amount of money you would generate in the long run. 

2. IoT based pollution detection sensor and dashboard to monitor pollution levels

 You are living in a city where taking a breath is getting difficult? Or you happened to be curious about what is the level of pollution that you face daily? For any use case, all you would need is your Arduino board and a little creativity because you would be able to create a pollution meter with the help of both.

You can even share your pollution meter results online to help your friends and family know when to wear the pollution mask. However, you would need two sensors as well because, without it, your board will not be able to measure anything.

You would need one sensor for gas   (MQ135) and one sensor which would be used to measure PM 2.5/ PM 10 particles, which happens to be the most omnipotent atmospheric pollutants. You would also be needing to use the Blynk app, through which you would be able to create some really stunning looking dashboard which would be displaying all the data pertaining to the project.

3. A project which would measure the level of the spirit and the range.

You will be killing two birds with one stone if you happen to do this project. You would need the power of the HC-SR04 ultrasonic sensor, with the help of which you would be able to measure distances in the range of zero to four meters.

This sensor would also act as a spirit level sensor. The construction of this project is not simple by any means, and you should remember this when you are out building this project for yourself. You would probably be required to make your perplex casing. However, to shine like a diamond, you would have to burn like one, meaning you would have to endure hardships to see this project thoroughly.

Since the coding is not too complicated, that means you get some respite there so, and if you are looking for a project which would help you to see the wide range of applications that Arduino has, you should do this project. 

4. Geiger counter

This project is for the sci-fi lover in you. Suppose you happen to love the movies where the protagonists venture into the unknown just with a clicking machine in hand. That machine is called a Geiger counter.

For the fans of Chernobyl (not the accident the series), this counter should be awfully familiar. You can create one for yourself with the help of your Arduino board. You will find that creation of such a contraption is not very difficult.

5. Text to speech converter

Yes, you can create an NLP (natural language processing) sized project with the help of your Arduino boards. There, however, would be many steps involved in the process. You would need to convert all the symbols into something that the machine would be able to understand.

And would have to convert the text into a phonetic script, and then you would be needed to convert them back into the spoken voice. Once you have set this up, you will have a text to speech converter, which would be able to play you back any messages or any text documents which you would want it to do.

6. A dustbin which happens to be smart

When you are trying to make various devices smart, a dustbin probably is at the last of your list. You can, however, make one dustbin which will remind you when it is filled, and it is time for you to take the trash out. That is not all that this smart piece of tech would do.

You would not need to use your hands or your legs to open the lid of the dustbin. You can easily program the Adruino in such a way that when it detects some particular range of motion. Let us say that you would want the lid to open when the Arduino would hear a loud clap or when you tap your foot anywhere near the dustbin.

With the help of code, you would be able to create such a dustbin. However, this project would not be completed without the help of Arduino Uno, which is a whole different breed when it comes to Arduino boards. Since you would be using such a complex array of machines and moving parts, this project would definitely not be the easiest thing that you will ever make.

But, this could prove to be a very useful thing because now you do not need to use your arms or your legs when you are throwing something away in the dustbin. This could prove very useful in high-risk areas like a hospital where even the smallest mishap could lead to an outbreak of a deadly pandemic.
