Wiring
When the slide switch is toggled to the right, GP12 is high; when toggled to the left, GP12 is low.
Each of the three buttons is connected to a pull-down resistor, GP13~GP15 are low by default; when the button is pressed, GP13~GP15 are high.
Code

After connecting Pico W, click the Start button and the code starts to run. Pressing different buttons or toggling the slide switch will produce different drum sounds, just like a drum kit.
Note
If you are using a computer, you will need to plug in headphones or audio to your computer to hear the sound emitted.
