Lesson 15: Sound Sensor Module (analog and digital output)

Please select other codes for this lecture from the links below.

This is the Arduino code Control AC Bulb with hand Clap or Voice (Advanced: Analog) This video shows you how to turn an AC light ON with clap or your voice and Turn it off with another clap or shout. This code is Advanced version where Analog output A0 of the module is used. Please see other version where DO pin is used to control light.
