All you’ll need in addition to the Arduino (or really, any modern microcontroller) is the sound sensor — which are often sold as “microphone shields.” To trigger the flash while still ...

The microphone sound sensor – Grove Sound Sensor (v1.6) – is built around the popular dual-op amp IC LM358 and provides an analog signal output. The recommended operating voltage is 5V what makes it ...

Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

A silicon microelectromechanical systems microphone is described that detects sound pressure gradients. The diaphragm consists of a stiffened plate that rotates around a central axis in response to ...
