Explore practical Arduino Nano projects focused on compact, low-power, and space-constrained designs. Arduino Nano is commonly used in embedded systems where size matters, while still offering full Arduino compatibility.
These projects demonstrate how Arduino Nano is applied in miniaturized electronics, sensor-based systems, wearable concepts, and custom PCB designs, with complete code and circuit diagrams provided.
Ultrasonic sensor, also known as a SONAR sensor is an electronic device that is used to measure the distance of a target object by emitting ultrasonic sound waves. Apart from distance measurement, it is also used for object detection and obstacle avoidance robots. Previously, we used an HC-SR04 Ultrasonic sensor with Arduino and other…
The need for home security alarm systems nowadays is a serious demand. As the number of crimes is increasing every day, there has to be something that will keep us safe. A motion sensor dog barking alarm can be a great choice for that purpose. The sound will alert you when someone approaches the house. They can also deter burglars from deciding to enter a home.

Most connected IoT devices today are connected to the internet using a Wi-Fi connection. Although a Wi-Fi connection enables remote access to the internet, it has its own limitations. For instance, in most industrial applications for a stationary device, Ethernet is usually chosen over Wi-Fi connection simply because it’s more reliable and secure. Also, since Ethernet is a…
Obstacle detection is one of the major concerns for a blind person. Presented here is a smart blind stick using Arduino Uno and Ultrasonic sensors. The primary goal of this project is to assist blind people to walk with ease and to alert them whenever their walking path is obstructed by other objects or people. As a warning signal, a Voice module is connected in the…
An infrared sensor is an electronic module that is used to detect the certain physical appearance of its surroundings by either emitting and/or detecting infrared radiation. IR sensors can also sense motion and determine the amount of heat released by an object. These sensors are commonly used in intruder alarms, light switches, and other home automation and industrial…
Who does not love photography! There are lots of subjects in this creative field and each one is unique, let's choose one. How much all of us love to see wild animals on National Geography or Discovery channels? Yes, I am talking about one of the widely cultivated genres of photography as well as one of the most dangerous photography subjects that is Wildlife Photography. In…
RFID (short for Radio Frequency Identification) tagging is an ID system that uses electromagnetic waves in radio frequency to transfer data. A simple RFID system consists of just two components: the tag itself and a read/write device. The read/write device consists of a Radio Frequency module and an antenna that generates a high-frequency electromagnetic field while the tag…
In industrial automation and control, PID controller has become one of the most reliable control algorithms that can be implemented to stabilize the output response of any system. PID stands for Proportional-Integral-Derivative. These three types of control mechanism are so combined that it produces an error signal, and this error signal is used as feedback to control the…
If you are a maker like me and looking for some interesting projects online, a milliohm meter is one easy and useful thing you can make. The basic principle of this circuit is based around a constant current source, which we have covered in one of our previous articles. A milliohm meter is a device that can be used to determine the values of small resistors, the resistance…
In this tutorial, we are going to talk about fuses. Back when I was in college and learning about all the cool things in electronics, I heard the term fuse in AVR for the first time, my initial thought on the topic was, oh! there is something inside the AVR that will blow if I did something wrong. Back then, there were not much resources available on the Internet…
An electronic scoreboard is one of the most important gadgets anybody can have during any sports tournament. Old manual scoreboard using conventional methods are very time consuming and Error-prone, hence a computerized scoreboard becomes necessary where the display unit needs to be changed in real-time. This is why in this project, we will be building a Bluetooth…
The earth’s Atmospheric CO2 level is increasing day by day. The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million and in October-2020 it is 411.29. Carbon dioxide is a key greenhouse gas and responsible for about three-quarters of emissions. So CO2 level monitoring has also started to gain importance.
In our previous…
