I want to follow along with something like this

my question is, how do i go about getting the functionality of something like this

where you have a physical knob you can turn to adjust the sensitivity

Hi jma00,

Adding in a knob to adjust the sensitivity for this project is going to be pretty tricky depending on your knowledge of the circuit and the electronics involved. The project uses the GATE pin on the Sound Detector which is a digital output so you will need to add in a way to adjust the GAIN of the Sound Detector. We cover this a bit in the [Sound Detector Hookup Guide so if you have not read through that tutorial, I would highly recommend doing so before starting this project.

[This comment from the Hookup Guide covers a similar question to yours in order to add a potentiometer to adjust the gain on the fly. The tutorial linked in Byron’s reply to that comment goes over how to make one with SparkFun parts and also includes a short bit on how to integrate it with the GAIN resistor on the Sound Detector [here.](Rotary Switch Potentiometer Hookup Guide - SparkFun Learn)](Discuss Tutorial: Sound Detector Hookup Guide - SparkFun Learn)](Sound Detector Hookup Guide - SparkFun Learn)
