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 ...

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 ...

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, ...

[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 ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it’s his ...
