Piezo Drum Lights Arduino code help!

Hey Stephen,

good news!

the code works! I did some rewiring and it appears I may have had one of the wires in the wrong port. My sincerest apologies for that.

I am now fine tuning the threshold and so far so good!

My next step is to connect an LED strip to this circuit.

am I correct in just doing so and including a MosFet and 12v power into the breadboard in the circuit?

Let me know.

Cheers again!

Yes a MOSFET will work to provide 12v power, and can be ‘switched’ by the digital out from the Arduino. You can certainly test it in a breadboard but I caution you that a breadboard can only handle so much current.

Breadboard is commonly rated for five volts at one amp or fifteen volts at one-third of an amp , both of which have a power dissipation of five watts”

This means that you should solder your MOSFET rather than use a breadboard for those connections.
