Project: Create sounds with piezzo and self-made pressure sensors

Projects General Guidance

SimzZafari:

  1. How do I include the force-sensitive sensors into the circuit? Are pulldown-resistors needed?

  2. Is there a way of creating a repeating sound with the piezzo, without using those pulldown-resistors?

  3. The Code... I got the feeling that I know exactly what I want my project to do, so I got a plan of how to start with the code, but to be honest I am not quite sure, if the stuff I want to do is possible with the assets I have...

Usually pullup resistors are used, just to keep on pin of the sensor on Gnd.

  1. See my reply #1
  2. No pulldown is required for the piezo. See tone() and noTone() in Reference for generating sound.
  3. See the button examples in the IDE.
