Used to detect the intensity of the ambient sound. Output: digital signal (LOW / HIGH). The triggered threshold is adjustable via a built-in potentiometer. Sound Sensor for Arduino, ESP32, ESP8266, ...

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards, and ...

This project uses a sound sensor to control an LED with an Arduino. The LED lights up when the sound sensor detects noise above a certain threshold, making it a fun way to create sound-reactive ...

This project is an interactive Arduino-based piano that plays musical notes and a song stored on an SD card. It also includes a sound spectrum visualizer using an LED matrix, which reacts to the audio ...

[Tobe] has an intervalometer for his camera, but he wanted a device that could trigger the shutter using several different methods, not just time. He calls his creation the Megavallometer, which can ...

Electronic systems can help the visually impaired. This innovative project combines an Arduino Nano, a TCS34725 color sensor, and a buzzer to assist users who have trouble seeing colors. How can a ...

Development company Mr. Sensorium has this week launched a new Kickstarter campaign to raise the required funds it needs to take its Arduino mini sensor in the form of the MozziByte Mozzi Arduino ...
