Guys I want to make a circuit which turns ON a light and and simultaneously turns off a fan on detecting the sound from an alarm clock. Please help me. Is it possible to get a high signal always when the alarm sound is pulsating type one. I was planning to do this with a microphone. Later i found that there is a sound detector module available online. Is it possible that the sound detector module output will be high even the sound is a pulsating one
Pls suggest some ideas and circuits
