Request buttons #233

Good day sir. I have requested a new code for all types of Arduino. Can you make it as "Piezo Sensor to Button Switch or Mapping"?

I want to make a D.I.Y. Table Top E-Drum like this (Attached Photo)

I am not sure if I understand your request correctly, but you should be able to map that signal to multiple buttons. Just connect the sensor to an analog input and use the arduino function https://www.arduino.cc/en/Reference/AnalogRead to get the sensors value.

Then you can simulate a button press via Joystick.pressButton(x) if the value is < 100. Another if the value is < 200, < 300, < 400... as an example. And depending on the sensors intensity another button is pressed. Or you can map all inputs above 0 to a single button.

I've never worked with a piezo sensor, so I can't recommend any code basics. You may find some help over in the Arduino forums :)

This library does not focus on how to read values from input devices. It only focuses on making the Arduino appear to the host device as a game controller / joystick.
