This is a fun-loving project based on the Arduino platform. The project creates color light effects with sound level sense by an onboard condenser microphone. The project consists 20 x WS2812B RGB LEDs, an Atmega328 micro-controller, condenser microphone along with pre-amplifier, RCA connector, and trimmer potentiometer to direct feed audio. The project can be used […]
Reality AI’s Automotive SWS features Sound-based Detection
https://www.electronics-lab.com/reality-ai-automotive-sws-features-sound-based-detection/
Detection through cameras and lidar could be efficient but it has some drawbacks. As it requires visibility of the object within its range, thus detection is difficult for invisible and hidden objects. Radar could be an ideal choice for overcoming these drawbacks but it struggles with distant objects as it is incapable of the corners […]
The Chirp Explorer Board, a first for data-over-sound.
https://www.electronics-lab.com/chirp-explorer-board-first-data-sound/
The Chirp Explorer Board is the first IoT prototyping platform that’s tailor-made from the ground up to explore the possibilities of acoustic data transfer. Built around the powerful Arm Cortex-M4 CPU with inbuilt DSP for optimised audio processing, it allows developers to quickly and easily integrate data-over-sound technology into embedded scenarios. Freely-available reference designs and open-source sample […]

https://www.electronics-lab.com/soundcam-world-first-true-handheld-sound-camera-everyone/
Every day of our lives we get bombarded with different sounds around. Loud music, radio, people talking on their phone, automobile, traffic, and those unknown late night quacking sounds. All of these sounds are what makes our day to day activities, and we have even gotten accustomed to most of them and rarely get disturbed by them. […]
World’s Smallest MEMS Micro-Loudspeaker Saves 80 Percent More Energy
https://www.electronics-lab.com/71210-2/
STMicroelectronics along with the audio company USound has created the first MEMS (Micro ElectroMechnical Systems) micro-loudspeaker based on semiconductors. It’s the smallest loudspeaker in the world, but it can produce a powerful noise. MEMS makes it possible. The speakers are being presented at CES 2018 in Las Vegas. In the audio world, the electromechanical capabilities of MEMS have only been used to […]
