Audio Electronics deals with the circuits that are designed for converting sound/pressure wave signals to electrical signals, or vise versa. These circuits are used to processes and manipulate audio signals to design different types of audio amplifiers, audio mixers, frequency controllers etc..
This section consists of a huge collection of audio circuits with schematics and detailed explanation, to help you build Audio projects and use them for your Audio designs.
Hello everyone! In this project, we will create a voice-activated office assistant using the Maixduino board and generative AI technology.
The basic idea is simple: when the user asks a question using the Maixduino board's microphone, the device will capture the question, send it to a knowledge base (using basic data from the DigiKey…
Planning to buy a small voice recorder to record voices or sounds in an environment and store them in its memory? Think again! You can easily build your own voice recorder by following a few simple steps. This project focuses on building an Arduino Based Voice Recorder, which can also be abused as a spy bug. Our spy bug uses a small microphone…
As the winter season approaches, comes the festival of lights in INDIA. Yes, we are talking about Diwali, known for lighting up firecrackers. But they don't just light up the party; they also cause air pollution and bring health issues. So, to reduce pollution and improve our health we decided to build an Electronic Firecracker using Arduino which makes a loud sound…
In this article, we are going to discuss how to transfer audio through laser light. This is a fun little project, and the concept is similar to what we see in fibre optics cable. We will use a laser light to send data from one point to another. To be particular, in this project here, we are going to transfer our voice from one point to another by shining a laser light on a solar panel. This…
As you may know many of our everyday appliances or devices such as smartphones, home automation systems, smart speakers, headphones and many others have their own built-in microphones to capture the audio data. And if we look at them there are different types of microphones available, such as condenser, ribbon, dynamic and MEMS. Most modern devices like smartphones…
Adding sounds or music to our project will always make it looks cool and sounds much more attractive. Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra SD card module and a normal speaker. In this article I will show you how easy it is to Play music/add sound effects using…
Maker Jamie Matthews has recently created a new supercapacitor-powered speaker that significantly enhances charging speed and playtime duration. This speaker charges remarkably fast, achieving a full charge within seconds, and offers a minimum of six hours of continuous playtime without the need for solar power. This efficiency is credited to the use of a TPA2013D1…
Virscient, a New Zealand-based company, has introduced a cutting-edge wireless audio technology that facilitates live performance and gaming applications featuring exceptionally low-latency audio over low-power wireless connections. This innovation, known as the "LiveOnAir" module, is specifically tailored to address the demands of…
The maker Daniel Ramsgard has created a unique pair of glasses called ‘Sonic Sensitivity’. The Sonic Sensitivity is an audio assistive eyewear for the Deaf and Hard-of-Hearing individuals. Sonic Sensitivity will help them by using voice-to-text conversions, bridging the communication gap between the hearing-impaired and those around them.…
There are many ways to communicate between a product and a user, but the most common and popular choices for audio communication is the buzzer. The buzzer plays a very important role in electrical and electronic devices. We often encounter buzzers in common devices such as alarm clocks, doorbells, or other household appliances.…
The Bluetooth Amplifier Module is useful for DIY projects for creative and hobbyists. The module’s Bluetooth connectivity makes the project connect wirelessly and gives hustle-free entertainment. The board can work on Lithium-ion/Li-Po or Lead Acid battery, which is used to make the device portable. Its design makes it easy to implement…
For those who love tinkering with electronics, making a Bluetooth speaker from scratch can be a satisfying and fun experience. In this article, we'll learn a step-by-step guide on how to build your very own wireless Bluetooth speaker using basic electronic components under 9$ or 700rs. We have previously built many audio-related projects…
