In this post I am going to show you how to make a simple sound activated electronic switch on Arduino’s microcontroller platform. Seeeduino Nano (v1.0) ... Grove Sound Sensor (v1.6) The microphone ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, ... lets overbuild because someone cant build with $4 in parts,555, mic,resister, cap.

Users will need to provide their own Arduino Pro Mini and the hardware features a 1.4 W, 8 Ohms, Texas Instruments TPA2005D1, 14 bit ganged PWM, PWM 8 kHz low pass smoothing filter all powered by ...

For one, the sound doesn’t directly control the solid state relay used in the fan controller. When the microphone equipped Arduino detects enough noise, it will start a timer that keeps the fan ...
