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, ...

In my undergraduate years I learned programming Arduino Boards. After I graduated I decided to implement a music visualizer at home using a led strip, Arduino board, and a sound detector. I used ...

This Arduino project controls the brightness of an LED based on input from an ultrasonic distance sensor and a sound sensor. The LED's brightness is dynamically adjusted according to the distance ...

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 ...

I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...

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 seeing-impaired person select clothes with matching ...

Chirp and Arduino have announced the first official integration of data-over-sound on Arduino’s range of boards. The integration allows Arduino-powered projects to send and receive data wirelessly ...

To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter ...
