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.

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

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 ...

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 ...

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 ...

Make shows off how to build your own version of that device that's a little smarter and more useful. Make's guide uses an Arduino so you can set specific sound pattern for each outlet in your house.
