I2S is an Inter-IC Sound protocol that is used mainly to transmit or receive the audio data in a synchronous serial port between two devices. There are many applications where audio communication is required in digital devices such as adding a microphone or adding a speaker output to play some audio.

There are multiple Audio protocols available in…

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…

In this DIY, we are going to make an IOT based smart garbage alert system using Arduino uno that will tell us that whether the trash can is empty or full through the web server, and you can know the status of your ‘Trash Can’ or 'Garbage' from anywhere in the world over the Internet. It will be very useful and can be installed in the Trash Cans at public places as well as at…

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…

 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…

Telegram is an optimal application to combine with Raspberry Pi for all our mobile control purpose. It has very good developer support and lots of features are being planned to be released soon to enhance the performance of Telegram Bots. In our previous tutorial we learnt how we can set up a telegram bot for raspberry pi and also learnt have to have a chat with it and share…

Today we are building a very useful project in which we can control the LED lights using our voice through Smart Phone. In this project, we will send voice commands from Smart Phone to Raspberry Pi using Bluetooth Module and Raspberry Pi will receive that transmitted signal wirelessly and will perform respective task over the hardware. We can replace the LEDs with the…
