Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million). This circuit triggers the Buzzer when Smoke level…

Knowing the whereabouts of a particular object/person has always been comforting. Today, GPS is being extensively used in asset management applications like Vehicle Tracking, Fleet Tracking, Asset monitoring, Person tracking, Pet Tracker etc. For any tracking device the primary design consideration will be about its battery expectancy and monitoring range. Considering both,…

RFID stands for Radio Frequency Identification, it’s a very simple and inexpensive piece of technology that can be used to make applications such as RFID Based Door Lock, RFID based Attendance System. If you search online for RFID Based Projects, you will find many projects that are associated with security and tagging which might make this interesting module appear…

Ever thought of designing your own IC for a specific boolean logic application? Say you want to design an IC where it dispenses Tea, Coffee, Milk-based on the input choice given in an automated cafeteria or you want to actuate mechanical components/light/tasks depending upon the conditions. Boolean logic plays a major role in our day-to-day life. Well, boolean…

Humidity, Temperature and Pressure are three basic parameters to build any Weather Station and to measure environmental conditions. We have previously built a mini Weather Station using Arduino and this time we are extending the weather station with Raspberry Pi. This IoT based Project aims to show the current Humidity, Temperature and Pressure parameters on the LCD as…

 Since the coronavirus outbreak, building a contactless body temperature monitoring system has become essential for identifying those affected by the virus.  To solve this issue, temperature devices are often used to measure body temperature. These devices have non-contact IR temperature sensors that can measure the body temperature without any physical contact.…

Speech recognition technology is very useful in automation which not only gives you hands free control over devices but also adds security to the system. Apart from making voice controlled gadgets, speech recognition also provides significant help to people suffering from various disabilities.

In previous projects we built Arduino based Text to…

Arduino is very popular for building hobby projects and games, and we have previously used Arduino to build Snake game, Ping pong game, Space race game, etc. Today we are building one more popular game using Arduino- Buzz wire game or Steady hand game.

For this project, we will use an Arduino Uno, Buzzer, and two Aluminum wires. A 16x2 LCD is also…

We all have played Rock, Paper, and Scissors game at least once. It’s a very simple game where each player picks one of the three objects (Rock, Paper, and Scissor) making the appropriate hand shape on a count of three, and these rules are applied to decide the winner:

So in today’s tutorial…

Thermal imaging is considered to be one of those state-of-the-art technologies in computer vision that in the modern-day scenario finds its application in various places. As the pandemic situation worsens in 2021, more and more noncontact temperature detection tools are in demand. A thermal temperature sensor that can measure the temperature of the human body can…

The coronavirus disease (COVID-19) has seriously affected the world and there is no end to it. To limit the spread of the virus, mandatory face-mask rules are now becoming more common in public places around the world. Additionally, many retail stores and other public service providers require customers to wear face masks.

In today’s tutorial, we…

Have you ever thought of controlling any peripheral from anywhere in the world? Yes the IoT (Internet of things) has made this possible to control any appliance from anywhere and there are many IoT hardware and cloud platform are available to achieve this. We have covered many IoT applications in our previous tutorial. Today we will use Google Firebase cloud to control an…
