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 ...

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, ...

Car Parking Sensor with Arduino and Distance Sound Effects This project implements a Car Parking Sensor using an Arduino, featuring distance-based sound effects. The system helps drivers park safely ...

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 ...
