As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

He hooked up a microphone and a photodiode to the Arduino, allowing him to use both sound and light to trigger his camera, depending on which mode he selects.

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons.

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 ...

Created by Rabid Prototypes the Arduino development board allows you to easily add light, sound and motion sensors to your creations and is powered by a 48MHz 32-bit ARM Cortex M0+ micro ...

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 ...

For parts, I needed three things: a sound sensor, a computer brain to run it and a place to store the data. The best-known tool of the open hardware movement is the Arduino, which costs about $30 ...
