Introduction: 2 Minute Clap Switch
This simple 3 component circuit can be used as a microphone alarm or as a light switch. The way the alarm program works is that it detects changes in sound level and then triggers the light to come on for 5 seconds once the sound level has gone up by 2 or more units.
The light switch works in a similar way except that every time loudness level changes by more than 2 a boolean changes state thus turning the LED on if it was off or off if it was on!

High, very nice work.
Very elegant Coding.
Do you have some tips for adjusting the microphone?
My microphone only reacts when i blow on it (some strange i think).
I would appreciate a little help, thanks alot and best Regards

Wow! nice and simple! Could I do this with any simple arduino microphone breakout unit? What should I change if I would add my 5metres of LED strip light?

Interesting build! Here's an instructable on how to use the editor in case you want to get rid of that extra step at the end: https://www.instructables.com/id/How-to-Make-an-Ins...

I like how simple yet effective the program works.

Yea took a while to get the calibration and the Serial port out of it. . . . and when you teach programming to 11 and 12 year olds... simplicity is the way forward!!
