Top Best 99+ Arduino projects for Beginners & Engineers
Are you in search of the top best Arduino projects? If yes, then keep reading this post, it can be assured that you would choose one of the mentioned projects below for you.
Arduino projects have revolutionized the electronics/ electrical engineering projects and DIY sector in the present day. First-timers can find these projects quite engaging, especially if they are building their first project. You would be best off choosing Arduino projects if you have a specific interest in technology and wish to do interactive projects with it.
Now take a look at what Arduino has to offer and why you chose it?
Why only Arduino projects?
Arduino as a microcontroller being used in projects over the globe for a long time now. It also has a huge online community for supporting each other in hardware and code debugging. These community members are active learners, experts, professionals, and Arduino programmers. The Arduino hardware and Arduino software IDE is open-source and thus low cost.
Below are the features that made it popular:
- As compared to the other micro-controller platforms it is very cheap. Arduino boards start from less than $25 for Arduino micro from the official website, but the Chinese made boards even cost half the price of that.
- The Arduino IDE is a cross platform program and supported by most of the operating systems, also has third party online editors/ simulator like: free online simulator wokwi (In this simulator you can change the sensors and also edit the code to get the result), also implement the project before actually made it with real modules and components.
- Open source and extensible software that can be expanded through libraries. It has a simple and clear programming environment that is suitable for all types of users from beginners to professionals.

| Project title | Description |
|---|---|
| Gas leakage sensor using MQ-2 Gas Sensor | Any particular gas is detected using MQ-2 gas sensor, when the gas level greater than a preset level is detected then LED on the module is switched ON or an external buzzer starts ringing. Read datasheet for detail. |
| Fire/ Smoke Detection using MQ-2 Gas Sensor | Smoke is detected using MQ-2 gas sensor, when the smoke level greater than a preset level is detected then LED on the module is switched ON or an external buzzer starts ringing. |
| Obstruction detection with ultrasonic sensor | The ultrasonic sensor HC-SR04 sends and detects high frequency sound waves. Then detects the obstruction in the path without contacting it. |
| Distance measurement with ultrasonic sensor | The ultrasonic range finder sensor produces the high frequency sound waves and calculates the echo time, to determine the distance. |
| Obstruction detection with infrared sensor | The source transmit IR light, then reflected infrared light from the objects is detected by the sensor. Thus senses the obstruction. |
| Object counter with infrared sensor | The IR sensor has a Infrared light source, which bounces the infrared light from the objects to the sensor. If senses the obstruction then count it as an object, otherwise don't. Thus the number of objects is counted on each obstruction. |
| RPM counter with infrared sensor | It works in same manner as that of object counter, except you have to some arrangement depending on the rotating object. |
| Obstruction detection with Laser and LDR | The light source and ldr are placed in front of each other. The laser source transmit light , then received visible light from the absence of an objects is detected by the ldr sensor. Thus senses the absence of obstruction and vice versa. |
| RPM counter with Laser light and LDR | The light source and ldr are placed in front of each other. The laser source transmit light , then received visible light from the absence of an objects is detected by the ldr sensor. Thus senses the rotation. |
| Ambient Light sensor with LDR | It can be useful when we have to detect whether its a night (darkness) or a day (lightness). LDR module has an threshold controller to adjust sensitivity. |
| Thermostat with thermal temperature sensor | It is used to cutoff the circuit supply when certain preset temperature is reached. Its application is in water heater and other temperature control equipment. |
| Temperature measurement with thermal temperature sensor DHT11 | Exact measurement of surrounding temperature, the current though the sensor module changes according to the surrounding temperature, thus can be measured by Arduino. |
| Sound detection using microphone sensor | Upon reaching a certain threshold of sound intensity, the digital output sends a high signal to the Arduino can be utilize for clap control switch. |

If you are an absolute beginner in Arduino and trying some Projects as an enthusiast, make sure you select a very simple project that has only one simple sensor to interface. This is because it would be relatively simple to code as well, if you are stuck somewhere then you can take some reference from arduino example project codes to complete the project.
And if you are an intermediate in Arduino and already did some beginners level projects then you must opt for projects with two or more sensors.
You can also suggest your ideas, discuss these Arduino projects, and suggest improvements in the comments section below. Based on your suggestions, with all new ideas this post would be updated continuously.
All the efforts have been taken to avoid repentance of projects. So, don’t get disturbed by similar type of entries 🙂
