Sound Sensor with onboard Relay Arduino Nano Shield
This sound sensor with Relay driver shield for Arduino Nano can be used to develop sound-activated ON/OFF switch or other projects that require sound senor. LM358 op-amp is used as the amplifier, 1st op-amp amplifies the microphone signal, and 2nd op-amp works as a half-bridge rectifier...
