Whistling detection Arduino

2. Arduino code

2.3 LED strip with MOSFET

Now, all we have to do is connect digital pin 13 to the gate of a N-MOSFET as in the schematic below. You could change the code in order to control all 3 colors of the LED strip. Make the connections below and upload the next code.

There you go, I can turn on and off the LED strip just by whistling.

Thank you for everything.
