Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using Arduino. This LPG gas leak detector uses an Arduino Uno and MQ-5 gas sensor to detect gas levels in the air and activates a buzzer and LED to alert users when a leak is…

It is important to know the different types of transformers for electrical engineering applications and to design power systems. Transformers are electromagnetic devices based on the principles of electromagnetic induction discovered by Michael Faraday, and they perform very important functions for power generation, transmission, distribution, and electronic circuits. This large reference…

Sound direction detection is a fascinating concept in robotics and automation. It allows a device to "hear" and determine the direction of a sound. This concept has numerous applications, including robot navigation, smart security systems, gaming, and entertainment. Earlier, we showed you how to measure sound in dB using Arduino. In this tutorial, let's learn how to find the direction of sound…

Diodes Incorporated has introduced their new Piezo Sounder Driver IC PAM8906, with Self-excitation and increased sound pressure level (SPL). It features an integrated synchronous boost converter and can be operated either with external pulse-width modulation (PWM) input or in self-excitation mode. This provides greater application…

There are several water fountains which unconditionally sprinkle water with some interesting lighting effects. So I wandered about designing an innovative water fountain which can respond to external music and sprinkle water depending on the music beats. Isn’t it sound interesting?

The basic idea of this Arduino Water Fountain is to take an input…

As a kid I was fascinated by a toy music car which gets triggered when you clap your hands, and then as I grew up I wondered if we can use the same to toggle lights and fans in our home. It would be cool to just turn on my Fans and lights by just clapping hands instead of walking my lazy self to the switch board. But often times it would malfunction as this circuit will…

One of the cool projects I always wanted to build is an FM transmitter with a good range. I have always been fascinated by some of the applications of the transmitter, especially when I was younger and, like everyone else, spent most of my time imagining how cool it would be to have some of the equipment and devices used in spy movies. So recently, while going over one of my…

Door Bells are available in lot of variations in market which generate different sounds but the most common sound of a Door Bell is “Ding Dong”, so this time we have decided to make a Door Bell Circuit with a Ding Dong sound by using 555 timers.

Amplifier is an electronic circuit or device which is used for amplification purpose and used mainly in sound reproduction as well in our electronic industry widely. There are many types of amplifier available by using different components like transistor based amplifier, op-amp based amplifier, transformer based amplifier. Sometimes we use a Preamp Circuit in circuits…

In this session we are going to use Raspberry Pi and the PYGAME functions to make a sound board. In simple terms, we are going to connect few buttons to the Raspberry Pi GPIO pins and when these buttons are pressed Raspberry Pi plays audio files stored in its memory. These audio files can be played one by one or they can all be played together. In other words you can press…

A lot of toys have some kind of melody tones in them. But how do these tones generate? Here we have designed a simple tone generator circuit using only a single melody generator IC.
