In this project, we are going to make an AC Voltage Measuring Device using Arduino, which will measure the voltage of Alternating Current Supply at our home. We are going to print that voltage on serial monitor of Arduino IDE as well as show on the multimeter.
Making a Digital Voltmeter is a lot easy than making an analog one because in case…
Stepper motors are increasingly taking its position in the world of the electronics. Starting from a normal Surveillance camera to a complicated CNC machines/Robot these stepper motors are used everywhere as actuators since they provide accurate controlling. A Stepper Motor is a brushless, synchronous motor which completes a full rotation into a number of steps.…
Detecting motions or movements has always been important in most projects. With the help of the PIR Sensor it has become very easy to detect human/animal movements. In this project we will learn how we can interface a PIR Sensor with a microcontroller like Arduino. We will interface an Arduino with PIR module and blink a LED and beep a Buzzer whenever a movement is detected…
Attendance systems are commonly used systems to mark the presence in offices and schools. From manually marking the attendance in attendance registers to using high-tech applications and biometric systems, these systems have improved significantly. In our previous projects, we have covered few other electronic attendance system projects using RFID and…
We all know about Arduino. It is one of the most popular open source micro controller board which is highly useful for doing DIY projects. This Arduino based 3-Way Traffic Light Controller is a simple Arduino DIY project which is useful to understand the working of traffic lights which we see around us. We have covered a more simpler version of traffic lights in this…
It’s all started with a small game from the dark ages called “Mario”, right from the time of being a tiny little guy jumping on ducks to save my princess till being a masculine handsome Prince roaming in Persia (Prince of Persia) fighting against darkness to save my world behind I have been a great fan of playing video games and I grew up playing them. But they do get bored…
We all are quite familiar with Electronic Voting Machines, where your vote gets registered electronically and you don’t need to use ballot paper to vote in election. Today security is a major concern and it also needs to be ensured that someone can’t vote twice, so this problem can be solved by introducing Finger Print Based Voting, where a person can be authorized based on…
Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In this post, we will…

In this project we are going to build a piece of entertainment using Arduino. We all have that habit of tapping Table or Pen for creating any random music. Of course it might not be considered as a good mannerism, but we all enjoy doing it at least once. Hence I thought of taking it to the next level by using Arduino’s ability to play tones. Once you build this project you…
As Engineers/Developers we always rely upon the data collected to design or improve a system. Recording data and analyzing them is a common practice in most of the industries, here we are building Arduino Data Logger Project where we will learn how we can log data at a specific interval of time. We will use an Arduino board to read some data (here temperature, humidity, date…
Arduino is an excellent way to simplify and speed up your microcontroller projects, thanks to its community of developers who have made almost everything look simple. There are lots of Arduino Projects out here for you to try and have fun. Some of your projects might need some sounds action to notify about something or just to impress the viewers. What if I told you…
