I am still receiving many requests to post an Arduino Sound Machine project. I think now is the right time to prepare a primer for beginners. First, keep your expectations low, as I don’t have ...

The 9V battery powered circuit produces a loud, wailing sound as a warning signal. As well, one red-colored LED (shines like a beacon) provides the visual alert. After construction and testing, you ...

A Repeating Timer (e.g. for sampling audio data using exact times) for TimerCallbackAudioStream; Desktop Integration: Building of Arduino Audio Sketches to be run on Linux, Windows and OS/X; This ...

Circuit Diagram: Circuit for this Arduino Sound Level Meter is a very simple in which we have used the LM386 Audio amplifier circuit to amplify the signals from a condenser microphone and supply it to ...

The URF is small, hand-sized Arduino project that measures the distance between itself and a still object using ultrasonic sound waves.. The device is powered with a Polymer Li-Ion Single Cell Battery ...

Open Sound Control (OSC) is a communications protocol that can be seen as a modern alternative to MIDI. It’s specifically designed to play nicely with network communication systems. The probl… ...

Some of you may remember the old SN76477, the famous complex sound generator from Texas Instruments. Originating in the 1970s, it allowed the creation of a variety of sounds such as gunfire, steam ...

A typical Arduino microcontroller board is pretty small, about the size of a credit card. This makes it suitable for embedding into all sorts of electronic devices. But it's possible to go even ...

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 thi… ...
